When they say METAL bass is easy... 

A metal album from Charles in the future, who else would be down? 🤘

The only bad thing about this song is that it ends. I want more of this Charles!!!

I need more prog metal like this dude, this was INCREDIBLE

Watching Charles' growth in his craft in the last 2yrs. leaves me speechless. He's approaching Jaco/Berlin territory, where instrument is extension of self. The only thing lacking is stage/ audience and a good band.

The percussive part just locks in so tight with the drums. A+.

Your composing skills are insane, you are an inspiration Charles.

Man! You've become untouchable!

I'd legit want an EP in this style. Some of the best parts has a "Flea auditioning for Meshuggah" vibe. The more fleshed out backing tracks is a huge improvement as well.

Good luck actually being able to play something like this in a metal band without the lead guitarist crying about it.

Charles never disappoints and always delivers top notch virtuosity

This whole thing was mind blowing, but the last 20 seconds were whatever comes after the mind has blown...I don't know what that level is called, but it's awesome.

A really well-executed 7/8 6/8 4/4 metal song!

What an ABSOLUTE UNIT Charles is!!

Reminds me loads of the bass solos in an Infant Annihilator track or a Necrophagist track. Absolute king

0:32 for 2 seconds it reminds me of Dance of Eternity. Awesome as always CB!

Absolutely incredible work. Please more metal! This was great to listen to

This is actually what Jason Newsted was playing on '...And Justice For All' Sounds amazing as always, Charles!

I was gonna try and make a joke about bass being inaudible in metal, but your solo honestly left me speechless.

This has to be one of the cleanest and popping sounding bass playing ive ever heard bro. Seriously I'm blown away by your talent

YES. More of this please!! Wish there was whole metal genre based mostly on the bass like this one cuz it SLAPS

*You mean to tell me it isn't just playing open E strings????* Cheers Charles for another fantastic piece man!

Charles has to be one of greatest bassists of our generation. The amount of content with how technical the songs are is nuts! I don't know how you do it all.

I went back to some of your earliest videos just to see change in patina the on the base from your oldest videos to the newest. It's cool to see the evidence of all that hard work and gives the instrument some nice character.

I'm 51 and used to play bass way back in high school. Have always loved bass and love watching bassist play. You make this old man want to buy one and try again. Can an old dog really learn new tricks?

Wow, this would fit right in as part of an 8 minute Dream Theater song. Someone put John Myung on notice! Charles, would love to see you cover the bass intro to Panic Attack!

I think you have made the case here that you could play in a top level band of any genre

Please expand this. My speakers are in pain from playing it on repeat it over and over.

Holy crap that distortion sounds awesome!

Bassline was giving me some serious old school Opeth vibes, loved it

I'd love to hear you with Animals As Leaders. I think adding you to that sound would badass. Not necessarily joining them just hearing you guys jamming together.

the main distorted riff is awesome.

what did just happen there. that 3rd part is straight filthy, i love it!

0:40 Sounds like a theme to a boss battle! Than 0:47 he reaches his final form after beating his ass! And than 0:40 the theme repeats itself! Damn, music can tell a story lad! Nice playing!

Definitely seems more prog rock than metal, but doesn't matter. Kicks ass.

This one of the best bass souds i have ever hwart in my enteire live

I love he played so many slaps and pull offs that the paint wore off on that part of his bass, by the pickup...

You re amazing! 🇧🇷

When I got to know Iron Maiden and MetallicA back in 80s, I never noticed the bass. Partially because I had crappy cassette player, and I was mindblown by Bruce's vocal and James' riffs. For years I believed that metal was about vocal and guitar. Then I found Helloween in 1988. Markus Groszkopf opened my ears to metal bass. After that it's Steve Harris and Cliff Burton rediscovery for me.

The super quick scale at 0:58 literally takes my breath away.

The hardest part about metal bass is getting the bass player to hold down the roots instead of trying to add a piano part.

How are you not in a metal band? The bassist in Unprocessed is ridiculous this reminds me of that.

Woah! Now that’s the kind of talent and dedication that deserves millions of views. Thanks for sharing! Much respect from PA USA

We could have a bass challenge, split-screen, where I watch you play and nod my head in approval. Then when the screen cuts to me, you would see me taking my bass to the pawnshop and then walking away with my head down in shame. I so enjoy your videos.

*lockjaw :O wow charles you're an inspiration to me, to drop & stop playing my bass guitar. thanks!

Phenomenal. This is what expanding an art form sounds like (the ideas packed into this song could easily be 4+ songs if you take apart or expand or stretch or simplify some of these riffs, add another layer of simple guitar melodies/harmonies/fugue, and explore with dynamic drums over repeating/slightly different variations of those changing riffs, all for the sake of melodic tension/anti-climax/groove/drive/concept-the true masters are able to compose non-linearly, imagining the parts of a song like scenes in a great play or movie, all supporting one another, and coming together, as the method and meaning of the work). Now, all Charles has to do is joke-name everything that he writes. Because that's how you style on artists who take themselves too seriously, as well as, entire genres of music. This song could very well be named "Razorblade Gravy" or "Hammer Slapped Face" or "My Name Is Blood."

We are witnessing something very special. Charles is the best bassist that has ever lived. It sounds wrong in the first moment, because we have the Jacos and Victors etc. But Charles is the best of all of them combined. I am a pro myself, listening since iam 5 to bass music, studying the inner substance of the very best songs, so i know what i am talking about. I cant believe how fking good this dude is. Perfection in tone, groove, speed and virtuosity. plus he is also charming and funny.. dafuq!? I love u Charles!

The bassist of Jinjer has a number of one-take playthrough videos of their songs on the band's youtube channel. Charles the pro, you know what to do.

Every week is a WOW! WEEK with your minuets Mr Berthoud. 👏👏👏🔥

Easy to think it's easy after watching you do it mate people might not realize just how talented you are 👍

This needs to be a 12 minute piece with an epic songwriting arc

He's the squizgar squiggelf of the bass world!😆

Please, make more of these metal videos!

As a metal guitarist and composer bored of the standards of djent and metalcore... I gotta say I'm pretty impressed!

HOLY SHIT, Charles you outdid yourself here.

This is really amazing

I have never in my life been impressed so many times in a minute.

I'd love to see your process. How long does it take you to master a piece like this? How do you learn/write it? How many attempts does it take to record the audio? Do you edit mulltiple takes together or do you go for a perfect run? Is the video footage the actual footage of you playing or is it dubbed? I'd love to know!

I can't believe how musical and natural sounding all these flexing pieces are. That is a most unusual feature. Reminds me of JS Bach and I don't say that lightly.

Incredible. I'm inspired to work harder and improve. Thank you.

Thx Charles. This is awesome keep rocking bro

I’d love to hear what you could pull off in drop D or drop C tuning for metal bass lines!

Got-dang! That was crazy and djenty as all get-out, and still just on a 4 string! I'd love to hear a rendition on a 5-string with a low-B, but still - this was impressive as heck!

Love the 7/8 sections - absolutely phenomenal piece, Charles. I'm in shock, as usual, mate.

Пересматриваю, наслаждаюсь… чарлз крепкого здоровья тебе!!!🫶🏻

little bit too funky but its fuckin awesomee!!

Well, that was sure heavier than expected

I bet nobody else will ever played like u did.. Clean, full of technical ability.. And.....u are a living lagend!!

Dominic Forest Lapoint would be so proud! Great job as always!

Well, it's never easy if you're doing the work of the entire string section of the band 🤣

FINALLY!!!!!!! SOMEONE WORTHY OF PLAYING BASS!!!!!!!!!!!! My god! That was good ! 10 minutes straight would have been a minimum! Love it man! #BassGod

I need more of this.

Outstanding, sir. Congratulations.

Did he just... slap metal? Did he just... make it sound good?

I really start appreciating your tone and musicallity. Tapping takes some time to adjust to, but I start to hear your intentions now. Love it!

JEEEEEZ! That was amazing dude.. great job!

I must listen to that every three days three times in a row.

I would absolutely love if you cover some First Fragment Gloire Éternelle’s basslines but I don’t know if you have a 6 strings fretless bass tho

Cool stuff! Actually, when people tell me that Metal bass is easy, I show them the bass of Origin - Aftermath. Now I have one more video to prove them wrong! Thanks :)

Absolutely amazing Charles... 👏😁

That was insanely good

I want ten hour version of this .

Most underrated video on earth

Literally one of the coolest things I’ve ever heard you play. Hands down! Horns up!!! 🤘

Chucky boy, you make things look so simple and play so nonchalant. But that's what practicing regularly and committing to your craft does at the end of the day. Keep it going my man! You're a fucking beast!!!🤘👍🤘👍

I love how relaxed you are playing such riffs, I tend to stiffen up which obviously doesn't help fluidity, I need to remember this when playing

I would bet Charles would have SO much fun working with a band like Dance Gavin Dance.

Wow😮 absolutely phenomenal skills Charles 🎸

Brutal AF!!! Metal AF!!! Jus straight up BADASS!

Absolutely awesome! My favorite performance!

That signature "berthoud tap riff" progression making an appearance in every song is pretty neat. Always has a little different flavor.

Daaaamn bro, you're SLAPPING that bass!! 🔥🔥🔥🤘

Bruh. We need more of this.

I'd honestly love a whole album of this.

That was the sickest bass part I have ever heard! Epic!

This sounds like a great song for a boss battle in a video game.

This is so fkn heavy. I can’t stop listening to it.

This shows WHY I went to Metal: bass lines that are not boring to death! And I still don't regret my choice (after 20 years) :)

This is one of CB's stuff i like so much

That's straight up awesome to the core 👍👍

This is awesome! More metal bass solo please!!
