This is the WILDEST music I know 

Thanks to everyone who submitted a video answering the question 'What's the wildest piece you know' - I loved including everyone and was only sorry I couldn't include more. If you'd like to be involved in future participatory things like that do follow me on twitter (@davidbruce) or instagram (@davidbrucecomposer).

I think the Große Fuge is pretty wild. It sounds like Beethoven hurled himself through Bach and landed on his head in 1915.

My favorite wild music has probably got to be death grips. So gritty and stark, yet so damn groovin

The wildest piece is clearly John cage's 4'33" played on a giant construction site during a tornado.

The Rite of Spring must surely be mentioned. A ballet about sacrificial virgins which caused a riot at the premier; nothing tops that.

What comes up to me for its wildness… - Ferneyhough - La Terre est un Homme - Schnittke - Overture from Gogol Suite, Mvt.2 ‘Toccata’ from Concerto Grosso - Rouse - Gorgon - George Crumb - “Music of the Apocalypse” from Star-Child - Xenakis - Most of his orchestral pieces - Peter Maxwell Davies - 8 Songs for a Mad King

Camellia and the Hyperpop genre are so close to the edge of noise sometimes, it's incredibly wild and fantastic.

I really like free improvisation/free jazz; it's undoubtedly wild and wonderful. So I would like to recommend everyone two albums: one is Otomo Yoshihide's New Jazz Orchestra's 'Out to Lunch' (a rendition of Eric Dolphy's album), and Zeitkratzer's 'The shape of jazz to come' (an album of standards by a german ensemble which usually focuses on more contemporary music. It is unrelated to Ornette Coleman's album of the same name). I love both albums and I hope you like them too

A lot of moments from Captain Beefheart’s _Trout Mask Replica_ come to mind. And in a sense the music of The Shaggs - completely free of “what you’re supposed to do in music”. (Hah! I made this comment a couple of minutes before you mentioned both. Great minds think alike!)

My first thought would be something by Cardiacs - either The Duck and Roger the Horse, or Eat It Up Worms Hero. They have the compositional intricacy of prog rock, but the energy and intensity of punk or metal. The songs are, on first listen, completely unpredictable, changing key, time signature, and volume without warning. Cardiacs are my standard answer whenever someone asks me what's the weirdest music I like.

When I first heard Bitches Brew as a teenager in 1969 or 1970, I thought it was just unorganized noise. But with repeated listens due to my and my friends' quest to be cool, it grew on me. Now I wouldn't be surprised to hear it in an elevator.

Meredith Monk deserves a mention for wildest music. I would LOVE a David Bruce episode on Meredith Monk. She really deserves to be better known. Two songs to start with: Madwoman's Vision and Gotham Lullaby.

When John Coltrane performed Vigil live in Comblain La Tour in 1965... The beginning when it is a duet with the drummer, that dialogue between sax and drums is just so powerful. And then it transcends when piano and bass join in. The wildest music!

For me there are two "moments" in the pop era that depicts very well the ideia of wild: Jimi Hendrix playing live, which is the wild meaning "savage", and the instrumental mess in A Day in the Life, meaning "there's no rules".

I'm going to have to say the entire "Calculating Infinity" album by The Dillinger Escape Plan. I've never heard anything else that even approaches the intensity and chaos of that whole album. Especially when you see live performances.

Shostakovich 4 is definitely his most wild symphony.

Thanks for the Turangalîla shoutout! I think musical wilderness can go many ways - on one hand you have artists like Daedelus and Daisuke Tanabe who go to great lengths to micro-engineer a texture to the songs they produce. On the other, it's so fun to see bands like Sigur Rós or composers like Messiaen who wind you up with the sheer mass of their compositions. Stay wild, folks!

“Machine Gun” by Peter Brötzmann. I can 100% guarantee that listening to it all the way through in one sitting is one of the freakiest and most disturbingly beautiful musical experiences you may ever have!

Always amusing that Death Metal is seen as the wild end of music. Even Metalheads would easily and quickly point to Grindcore as far more against the grain, whilst still having the distorted guitars and heavy drums and gutteral growls. Death Metal is a pretty solid and straight forwards style of music, in the range of all that is music. I think one of my favourite bands for being wild, in my consideration, is Unexpect. Which, as the name implies, defies expectation. Until you've heard it a thousand times, of course. But that first listen hits you like a bus.

Black midi stuff bewilders me by its ability to sound conventionally good in some aspect while literally making laser sounds out of a piano. The few black midi renditions of Akasha by xi that are around on youtube just absolutely blow my mind.

I absolutely love reading through the comments and seeing all the different interpretations of wildness in all imaginable musical styles.

Lots of people have mentioned stuff I thought of, but two bands/artists I haven't seen mentioned would be British industrial black metal band Anaal Nathrakh and French experimental producer Igorrr. Anaal Nathrakh's music may not be as "brutal" as some others, but especially their older stuff is _extremely intense._ The first time I heard "The Supreme Necrotic Audnance", I was floored by the massive sound and sheer violence of the vocals, on a completely different level than most death/black metal or grindcore vocalists. They also slip into noise music at times, it's fascinating. Igorrr on the other hand is... odd. He mixes breakcore, black metal, baroque music, classical, jazz, triphop, operatic vocals mixed with guttural screams, and some properly odd stuff like putting a bunch of seed on a toy piano and recording the sound of hens pecking at it. And yet, it somehow works and is entirely listenable (and in my opinion, very good!) Some of my choices for songs by Igorrr would probably be "Tout Petit Moineau", "My Chicken's Symphony", "Cheval", and "Biquette" (feat. Ruby My Dear). :)

I've seen a few comments mention this but Pulse Demon by Merzbow is literally 75 minutes of ear-shredding static and feedback; basically an entire album of exactly the kind of sounds you usually avoid in music production like the plague. Also, in terms of stretching the definition of what music even is: Homotopy To Marie by Nurse With Wound. The first track, called "I Cannot Feel You as the Dogs are Laughing and I am Blind", is three minutes of metal crinkling sound, followed by five minutes of groans, then three minutes three minutes of chewing sounds. For best results, listen with the lights off.

Shostakovich's 4th and 2nd symphonies are pretty wild!

Saw the video title and Hocus Pocus by Focus was the first thing to pop in my head. Yodeling, Whistling, and just manic energy through out.

Expected you would mention 4'33''. It's a classic, still kinda wild

The opening section of Beethoven's Grosse Fugue is absolutely crazy wild.

Gotta say Schnittke's 1st Symphony, just an hour of stopping every 30 seconds to ask yourself what on earth you are listening to.

Wildest song I know is *SDSS1416+13B (Zercon, a Flagpole Sitter)* by Scott Walker. It's an absolutely insane, 21-minute masterpiece that skeeves me out every time I think about it - it's so out-there in the most inconceivable ways to me. I've definitely heard more complex songs before and since, but A Flagpole Sitter just goes for it so hard that it can't not take that top spot of "weirdest song I've ever heard."

Great video! If I were to add one aspect into the conversation, it would be wildness in sound design / production. IDM/Glitch/Breakcore music has been pushing that boundary for a while now. The wildest stuff I can think of right now is Dariacore, a genre consisting of hyperspeed song mashups with over the top synths, bass, and drums that is genuinely enjoyable to listen to. Not wild for wildness sake, but pushing the boundaries of music for the love of music.

I would say Threnody to the Victims of Hiroshima by Penderecki. Not only is it wild in the sense of going against commonplace musical structure and expectation, it chooses to tackle a very upsetting real event and really drive home the horrors of it. I's say it's wild in the sense that it takes something we wouldn't like to think about and places it center stage

I was gonna say either Penderecki’s Threnody, Miles Davis’s On the Corner, or Dillinger Escape Plan’s Calculating Infinity, but reading these comments, I realize there’s a LOT of wildness I need to explore (or had forgotten and need to re-explore!) 5 minutes in and I already know this is a video I’m gonna have to revisit many, many times! Absolutely golden! Thank you so much, David!

I've been listening a ton to King Gizzard and the Lizard Wizard's new album Omnium Gatherum. It's wild to me how many genres of music they cram onto a single album and all done at a high level.

In terms of pure wildness, I would have to say Merzbow - Pulse Demon album Japanoise definitely boils the rules in acid

Le Toit Du Monde - Gorguts. It is death metal but it's also one of the most intensely immersive experiences, still leaves me feeling absolutely bewildered, almost distraught, and I've been listening to it almost every week for 9 years since it first came out. Hell, the entire Coloured Sands album is its own unique experience.

Deathstorm (Maruosa & Bong-Ra) - We Are Deathstorm nothing has ever beaten that.

I will nominate Lost Rivers by Sainkho Namtchylak, a female Tuvan singer. Compared to a lot of examples in the video that are loud and cacophonous, it is just a single voice, however the quality of the voice is freaking wild (go have a listen you would agree). The wildest part for me is the simultaneous difference and harmony between the intent and the actual realisation - the intent being mourning the lost rivers of her homeland and advocate for environmentalism, and the realisation of noises and cries strengthens that perfectly. A truly amazing listening experience.

Before looking at other comments I also first thought of Merzbow's Pulse Demon. But for me the wildest piece that is more "comprehensible" that I periodically revisit is Karlheinz Stockhausen's Helicopter Quartet.

I'm going to go with Glenn Branca, Symphony No. 6 (Devil Choirs at the Gates of Heaven) as the wildest music I actually listen to by choice, though I was tempted by the rapid changes of John Zorn's Naked City, and if I didn't qualify it with "willing to listen to it by choice", I might pick The Resident's Third Reich 'n' Roll. (This comment made before watching the video, as requested.)

oh, and thank you very much for a very entertaining little show! Would have loved to hear the examples in full length but you put the adresses in the stuff below the window. Thank you again!

The Mingus big band can have a very wild and crazy sound with a lot of players doing something different but still in conversation. Haitian fight song and Moanin are good examples of this

A few come to mind; Jonchaies by Iannis Xenakis, Threnody for the Victims of Hiroshima by Penderecki, Aberinkula and Drunkship of Laterns by The Mars Volta, Alucard by Gentle Giant, Sugar and Vicinity of Obscenity by System of a Down, Nasty Habits by Oingo Boingo, Micro Cuts by Muse, Out of the Grave by Sigh, The Holy Drinker by Steven Wilson, Aumgn by CAN, Bring the Sun by Swans, The Girl in the Magnesium Dress by Frank Zappa, and Seven Words by Sofia Gubaidulina, and lastly, the band that took the peak intensity of Cannibal Corpse and did something different with it, it would be The Leper Affinity by Opeth.

Glad to see Nancarrow on the list, he was one of my first thoughts. Lots of my other ideas on closer listening weren't particularly wild. Intense, yes, but you'd struggle to call them wild in the same way that the pieces on your list are! Surprised no one mentioned any specifically aleatoric pieces though.

Stravinsky: Rite of Spring, with the lights OFF. Caused a riot at its premiere in Paris 1913 and still stands out today, its wild relentless and asymetric rhythmic drive and dissonance, deliberately evoking a wild Pagan and ancient ceremony that scandalised Polite Parisian sensibilities and expectations

Igorr's Hallelujah is the first thing that came to my mind reading the title of this video. I love a good chicken solo

A particularly wild band to check out is Clown Core. And their album/video Van is interesting to watch too.

I'm so happy you cited Liturgy! The level of rage they inspire in purist metalheads is a sure sign they are breaking fences.

I mean as an adult probably Threnody or some of Cage's work but I want to highlight as a younger man, a dyed in the wool metalhead at that (which means I learned a lot about human culture as a teenager THROUGH metal, not learned it outside of metal and then rediscovered it within a metal context) I think a seminal 'wild' piece of music that I still resonate with is the Austin Texas band Watchtower, their second album 'Control and Resistance' that came out in 1989 was definitely wild. It gave birth to the whole progressive metal thing, obviously, and today we could go back and listen to that music and classify it as some sort of fusion. And there's a *lot* of wild fusion, like proper jazz/rock/world music fusion that is wilder than anything any metal band could came up with. But 'wild' is about context, and in heavy metal context, against the conservativism of most rock music trope, Watchtower were fucking wild and they still sound wild. It's not just the riffs and compositions actually, it was their attitude and extra-musical elements that also gave that impression, such as, teenagers wearing USSR t-shirts during the cold war in Texas (even ironically, that's quite a statement!), the punk sense of humour that is antithetical to heavy metal seriousness, and of course the fact that they play this hypercomplex, flowing sort of metal but they're not robust and muscular at all, the drummer sounds like they're half improvising a song they don't remember, yet he's still in pocket. Control and Resistance captures the feel of the late end of the cold war perfectly, the musical programme and the thematic programme are in sync. Now we're heading towards more cold war terror, so the lyrics sound more prescient than ever.... sadly. It was a more abstract, complex and open to interpretation and mood kind of metal music that simply didn't exist before Watchtower invented it. It will always be the 'wildest shit' in my heart even now I have a broader musical horizon. Thank you for asking, David! You are a class act.

On a Mission by Drumcorps is definitely one of the wildest tracks I've ever heard

Wildest for me is pretty much anything from John Zorn's project Naked City. Seems that they recorded a bunch of sessions to explore exactly this idea... How wild can it get - pretty wild... and also the idea of using contrast with nearly normal snippets of coherence to stop you becoming completely desensitised to the wild crazy parts. Not sure which track to suggest though...maybe Snagglepuss?

Amazing list! I would propose Philip Glass's Opera "Einstein On The Beach" as a wonderful example of "wildness through repetition / composition", in a pretty transcendent musical depiction of genius and the miracle of consciousness.

Off the top of my head, in no particular order, here are some candidates (composers/artists rather than specific pieces) for "wildest music": - Merzbow - Conlon Nancarrow - John Cage (eg 4'33") - Throbbing Gristle (eg Tiab Guls) - Arnold Schoenberg (eg Pierrot Lunaire) - Anton Webern - Screaming Headless Torsos - Steve Reich (eg Pendulum Music) - Adrian Jacobs (David Lang) - Brian Ferneyhough - Ween

I love that there’s so much on RU-vid now taking theory based thinking and using it to try to understand why things work and derive new understandings. So much of theory is often presented as ironclad rules and that breaking them is bad but I think this kind of thing is exactly what makes theory so valuable. Thank you for making this kind of content

The wildest music I know is probably Gorgon by Christopher Rouse, its very vast paced and dissonant, and it moves between ideas rapidly. It's a work in 3 movements with these percussion breaks in between each movement, which adds to the overall chaotic atmosphere.

the shaggs - philosophy of the world. you truly cannot go wilder than that. it's so raw and primal

Ligeti: requiem Three screaming popes Rite of spring Einstein on the beach Four organs

Spike Jones is near the top of the list of wild music. Every note is played to perfection but with out of left field instruments.

Either general power electronics, Grindcore and it's derivatives, or one specific classically and jazz influenced death metal album, Imperative Imperceptible Impulse by Ad Nauseum. It's got right left ear dissonance, and all kinds of crazy shit. It's great, genuinely, and feels more like jazz than metal sometimes.

Love this video. I never really thought about different ways music could be “wild.” Also every time Dorian shows up in your videos it just melts my heart, such a cute little character ❤️

Gerald Barry has some wild pieces. Sur les Pointes is about the wildest I think. It has a section with the direction 'like a wild pianola' and it's ridiculous.

"Windowlicker" by Aphex Twin is pretty wild. "John McLaughlin" from "Bitches Brew" by Miles Davis is very wild. "Hajnal" by Venetian Snares gets a bit wild. "The Litanies of Satan" by Diamanda Galas is also quite wild. It's a wild world, just ask The Birthday Party as they "Blast Off!".

*Cheval* from Igorrr and *Threnody for the Victims of Hiroshima* from Penderecki are among the wildest musical pieces I know.

Back in the Eighties I was involved in a meditation group that imported rituals and meditations from various cultures. One striking moment for me was meditating to Tibetan Water Music. (I can't find anything online near it but instead I'm getting results for all sorts of 'soothing' new age sounds.) This 'music' was an intentional cacophony of noises, some sounding like the roar of an elephant alongside arrhythmic pulses from crashing gongs, wood blocks being struck and so on. It slowly faded in and then slowly faded out after it reached a peak for about five minutes or so. It was the avant-garde-est of avant garde music I'd ever heard. The intention, according to what we were told, was to clear out and purify the mind of thoughts. I wish I could find an example online but I simply can't. Everyone seems to think that Tibetans are all about gentle, soothing, meditating culture, and that's all the internet is presenting.

I have long thought that loading a mellotron with jet engine sounds would be a good start.

There's this moment in Shostakovich' violin concerto I really love and that I think fits some of the wildness criteria. It's a couple of minutes into the second movement, when the orchestra is heard in full force for the first time in the concerto. It's a big happy tutti, including percussion and a xylophone plonking away but there is something that makes it feel completely over the top, something insincere, like the music is just pretending. Especially after the dark and slow first movement, that just seems to drag itself forward for over 10 minutes. Add to that the dense texture, uneven rythm and technical virtuosity... It just sounds really wild to me, both in sound and emotion. I love it

I feel like as I listen to more music, my threshold for wildness gets pushed even farther. A few years ago, I would have said Torche and Floor were pretty wild and out there. Now, I've listened to things like Sore Dream and Lingua Ignota and Full of Hell, and Torche is almost easy listening. Edited to add: You mentioned Liturgy and I've been addicted to this album and I almost mentioned them also, except I listen to other death metal also.

This video is pretty wild, well done. I've learned and discovered so much, thank you

Meshuggah Bleed is pretty wild.. The rhythm, vocals, feel.. Everything!

I find the question itself a little hard to get to grips with. I'm strongly tempted to say Tallis' Spem in Alium, though I can't think of any way to defend that choice to others. But while I was a maths student I used to use Skinny Puppy as my studying music, because it would thoroughly overload the parts of my brain that deal with the concrete, and leave me in a better state to process abstractions. I think (my maths background is showing again here) that there's a great deal of duality in play: I often find big-C Classical music irritating because I can predict it too successfully, and randomness relaxing because I can, as it were, bathe in it. Intensity is found in some middle ground where I am actively tracking a lot of ideas without being too completely defeated…?

Frank Zappa's Yellow Shark, his formerly assumed unplayable composition made on the computer performed by the Ensemble Modern, G-Spot Tornado is sublime.

Amazing video thank you so much i liked how you explained the various ways to be wild in music it made me realize what type of "wild"music i llike that being said my wildest music pieces that comes to mind beside the free jazz and techno Mr bungle Clown core some Zappa/ Captain beefheart and of course the Shaggs

This was a fantastic video and I need to see share it and see it again.

What comes to my mind first, when thinking about wild music is Quest for Blood with Yukihiro Isso's self titled album. It's black metal mixed with Japanese folk music, manifested as shouts and more importantly an improvised sounding folky flute solo over practically the entire record, clashing heavily with the western harmonies in the metal parts. They also heavily feature strange piano comping just to make it sound even more unlike anything else. I discovered this album at a point, where I was starting to get a bit bored with music, feeling like I could pretty much predict what's going to happen even in extreme / avant-garde metal, which I was listening mostly at the time. This album felt like I couldn't figure it out even after countless listens and also kinda taught me to appreciate modern jazz and classical at the same time.

I listen to enough mathcore (car bomb, dillinger escape plan, converge) and dissonant death metal (gorguts, ulcerate, sunless) for them to loose some of their wildness. So I'll go with Girl with Mary Turner by Xiu Xiu or Do You Doubt Me Traitor by Lingua Ignota. Also can't believe no one mentioned Deathgrips yet (especially Steroids). also mount eerie's death is real is wild to me because it is the only peace of music so devastating

Wow, so many pieces and songs to listen to after this video. This video is kind of like opening a new section of an encyclopedia and coming away with so many ideas

Black Angel's Death Song by The Velvet Underground comes to mind. I would also like to mention the wide dynamics in Brian Blade's style of drumming, he can be very easy to the ears for some time and then, suddenly, blow you out of your seat. Thinking about the wildness in music, I suppose I like to be surprised or even shaken by music but to achieve that the music has to relax me first. Kind of walking in a Norwegian forest and suddenly hear a lion's roar. Contrast is key.

For number 5 I would add Jane Doe from Converge. First time I listened to it I thought it was deranged and pure noise, it takes a few listens to make out each element and I think it is mostly compositionally simple (compared to other wild pieces here) but that album takes noise to another level.

OMG, YES. you cant have a video on WILD music without mentioning "Camellia" Already earned my respect there~

The artist Jute Gyte makes some of the wildest music i know - it's heavy microtonal black metal which sounds crushing and brutal while also atmospheric in a distinctly alien way

A very enjoyable video, David bravo!

Kawaii is just the Japanese word for cute, and in English refers to a uniquely Japanese style of cuteness. Much in the same wat twee refers to a uniquely hipster/cottage core style of cute.

To me, Liszt's Dante Symphony was wild in the context of transcendence in 12:48 , where it transported you to the realm of hell and heaven. The Paradiso (3rd movement) is so majestic, ecstatic, spine-lifting; it feels like you're entering the gates of heaven.

first astonished and then amused by your geniousity … touched my heart with cannibal corpse reference

Late contributions to this catalog... But just in case someone else hasn't also proposed these-- Hans Werner Henze's ballet Undine (in sections, at least), George Antheil's Ballet Mechanique, Jonathan Sass' Meltdown, Jack Parton's 2016 Piano Sonata, and the joyous violence of Samuel Barber's Piano Concerto.

All I can say is Troutmask Replica had to be relevant to this conversation. Mosolovs Iron Foundry is really intense, completely atonal yet it can immediately grab the listener. Now, Blotted Science has some exquisite and supremely intense music, while Behold the Archtopus goes a bit too far and has issues... Also I think Cacophony (Marty Friedman/Jason Becker) specifically in their Speed-metal Symphony intro and outro, really push the envelope. Then again Jacob Collier modulating to quarter tones successfully is also far out there. Now ... On the other side, we can consider Wesly Willis to be quite wild (Birdman kicked my ads for example), and similarly I'd say Syd Barret, and other outsider music (Schuman included) ... Are quite wild in the sense that they come from a place where reality is breaking down Stokhauzen has silences way over a minute (and Id argue that makes it irrelevant)... Anyway, this more anecdotal but I remember having listened to a grind core tape. It had 20 or 30 second songs that were rather soundbytes, where they used very dense drumwork, heavily distorted instruments and even ... Someone blowing on a snorkel ... Which was rather silly to me, I listened to about 3 samples. Really interesting train of thought!!

Penderecki's Threnody, Crumb's Black Angels, Grisey's Vortex Temporum, Kodaly's Cello Sonata and pretty much everything that Sorabji wrote are pretty wild too! Not to mention some Metal acts like Imperial Triumphant's Goliath and the list goes on...

"computers" by ClownCore and right in the middle is one of the most beautiful sax solos ever recorded

wild music i remember: a lot of music pieces of schostakowitsch, the bands phantomas and jon spencer blues explosion, richard wagner in many cases like die wallkürea 1, akt, a trio washing machines filled with shoes and stones giving a polyrythmic concert at a minimal festival in my brain while dancing

"Coward Killing Time" by The Quick Brown Fox has got to be up there. It sounds dangerous but considering it predominantly features audio clips of the Heavy from Team Fortress 2, I'd put it in the "Wild and Fun" category lol

very interesting question...for my money I think combining the intensity of metal with the unsettling qualities (to Western ears at least) of microtonal music is going to be some of the wildest stuff. Cryptic Ruse's Projected Into the Complex Plane, off of Pineal Algebra, is one of the more listenable examples of this, while still being very challenging to the point of actually headache inducing. I love it.

You've done a great job on this video. It is a difficult subject to keep it interesting. Thank you.

Thank you for a great video!

Excellent video as always, though pretty surprised not to see any Sorabji, Finnissy, Ferneyhough or Penderecki in this list! RIP Birtwhistle 😔

I've recently gotten into the Bonzo Dog Doo-Dah Band. Most of the jokes in the lyrics still go over my head, but it is incredibly funny and wild music at times. I very much liked some songs off their album called The Doughnut in Granny's Greenhouse. Trouser Press and We Are Normal come to mind. Mike Oldfield - Amarok Legendary Stardust Cowboy - Paralyzed Captain Beefheart has been mentioned... Ornette Coleman, Charles Mingus have some wild tunes. Penderecki - Polymorphia

This video is so well documented and edited. Big thanks and big bravo!

Laura Nyro's stream of consciousness expression of temporary insanity through hatred and murderous intent in Tom Cat Goodby (1969) is intense and scary. Nyro is Songwriters Hall of Fame and Rock Hall of Fame.

Metal did move on quite a bit from just sheer intensity, but even in that regard Cannibal Corpse is not peak anymore. Grind and slam bands emerged soon after who pushed intensity even more, with improved production value (Insect Warfare for example). A different kind of intensity was explored by drone, psychedelic sludge metal bands and also math metal bands like Meshuggah and SikTh using more and more dissonant chords and unusual rhythms. Compositional wildness was explored by "avantgarde-metal" bands such as Unexpect, Pryapisme, Shining and Igorrr (who mixed up instrumentation also). Then later death metal also got to a whole different level with triggered drums and edited guitars with technical death metal - Archspire for example who fuse classical elements into it. Metal is such a rabbit hole I don't think anyone can fully explore it.

I can't pick a piece, but some of Astor Piazzolla's music has sections i would definitely consider "wild". The feeling i get from it is despair bordering on madness. I love it 🤭

Ivan Alexandrovich Wyschnegradsky - 24 Quarter-Tone Preludes for two pianos

The first part of Keith Jarrett's Vienna Concert is such an absolutely wild piece of improvised music. Forty minutes of pure musical and pianistic genius.
