Avi Kaplan sings two tones at once AND Kevin Olusola's amazing live cello beatbox 

So. Avi can sing Overtone. Kevin beatboxes, plays the cello, and is fluent in Mandarin. I just heard Mitch sing Defying Gravity. Kirstie is smart as all fuck, and Scott, well, his talent speaks for itself. Everyone in PTX is incredibly talented in a dear-sweet-baby-jesus sort of way.

I hope playing this made him at least break a sweat. Don't tell me he was also doing Calculus in his head and kneading pizza dough with his toes while performing.

Finally, someone who records on 16:9 ratio. Faith in humanity restored. Subscribed!

Avi be like: I gave that pitch an overtone, Pitches love Overtones Lol! And also, amazing cello playing Kevin! I really liked it! #i💜Bassists #Avi-ousily #BassCannonKaplan #Penta-Holic

Avi and Kevin are the best!!!!!

I'm sorry to say this but Avi and Kevin weren't made here on earth, THEY were sent here by some higher power

Avi I'm totally floored of what you can do with your voicebox...and Kev, i have never seen such a multi talented intelligent guy like you. absolutely enjoyed this video. i very much hope i can hear you guys live in Canada! you both are amazing!

Kanye should go to a Pentatonix contest. That way he can see what real talent is.

He creates an overtone "top note" and it makes it sound like 2 notes while he is only singing one. That takes some serious skill

Why am I not surprised that Avi could do this? He is AMAZING!!!!!!!

Holy shit, his rhythm and coordination are fantastic. Anyone who plays a string instrument and sings different rhythms know how difficult this is---and this is 10 fold harder!

He can do a MELODY on HARMONICS??? A legit melody??? This man... I have no words for the awesomeness. No words.

wow, kevin your amazing!

love love this group

you are so amazing… i can't imagine doing two things at once when it comes to music…. bravo

Tuvan throat singing! Avi is so cool!

It's not throat singing, it's overtone singing. Throat singing is much lower.

at first I was like I don't hear two tones but then I realized it was two tones😜

kevin olusola i have no words other than GENIUS!!!

THIS IS SO SICK BOTH KEVIN AND AVI ARE LIKE ALIENS OUT OF THIS WORLD REALLY OMG AMAZING LITERALLY MIND BLOWN

WHO CARES ABOUT REPLAY BUTTON,I BROKE MY WINDOW!!!!!!!

Kevin Olusola is phenomenal!

THIS IS AWESOME

Awesome talents man!

amaxing talents,thank you for showing it to your fans.avi,where did you learn how to make your voice do that,its similar to some recirding I heard from this engkish guy wyo went to mongolia to record the music of nomads,he got to travel with a family andvlived in their yurt.and I have bever heard a cello sound like that.i had a cuoice between violin and fello,I wishni had tried the cello first,I chose the violin because it would be easier tobcarry it to and from school on the cuty bus.but was lucky to have a great violin teacher.i still like the cello, a neighbirs daughter playsvahd someyimes I can hear her practice. I can jo oinger play the violin,it was a frusying blow after I had a stroke last year,I can hold it,hut cannot finger the notes very well,I cannotbplace my fingers correctly on the strings,I kniw where tonplace themkbut the fingers are not strong enough,intry not to get upset about it,just feel maybe the brain is still rewiring itself so just need to practice patience.i cried when I realized I may never play my lovely violin again .I hope to regain that ability wgain in the future.thanknyou for your wonderful music.listening to music I have incorporated into my therapy,I hope to go back to my alt2rnwtive therapy,teldenkrais bodywork,the lady go to for that has worked on violinists with injuries related to overuse or repetative motion injuries.she has been encouraging me to pick up the violin again.

love this!

Hey Josh, the annotation says "original song", but Julie-O was written by Mark Summer of the Turtle Island String Quartet in 1988. I think you mean "original version". :)

You should put links to there channels in the description.

I stand corrected

that was amazing ! ur nice !

Amasing

If you like the overtone singing, check out the great Kongar-ol Ondar (RIP) performing Tuvan throat singing.

Vertical videos are a crime.

The Snare Kevin uses at 4:33 for a second is fantastic. The K snare he pretty much always uses sounds great, but I think he should use the other one more often.

yes

Holy crap! What next? They can fly?

this is just amazing! haha

Wicked!

how the hell is that physically possible?????

If you listen closely, he concurrently sings the melody in a higher tone; it's just not as loud as the "weeeeeerrrrrrrrrrr"

epic!!

I wasn't able to do it last year. I can now.

Awesome:)

00:56-01:00 Good lord, that sounds insane!

If you like beatboxing i would like to introduce you to Reeps One and Babeli, nothing to do with Kevin he is a great musician great beatboxer , just showing you some artists from the Beatbox competition scene check them out they are really interesting

I keep replaying 00:58 to 1:00 *chills

Just because he can sing in alto doesn't mean he is one. He's a bass.

Actually, I believe 1sgirl987 was OBVIOUSLY being sarcastic. Also, He doesn't always sing in bass. Check out his own youtube account. I'm an alto, and he sings notes in my range for an entire song.

I never said he ONLY sings in bass. He has a rather large range and I am perfectly aware he can sing in the alto range. Another note, this is the internet. It's difficult to detect sarcasm.

HOW DO YOU DO THAT I WANNA LEARN THE OVERTONE

watch the performance with your eyes not through a damn phone

is that song kevin played an original composition? :OOOOO

Nah it was there It's in the higher, whistle like tone (which is the actually point of overtone, or throat singing) that did the melody of lion sleeps tonight.

In Mongolia they do that two tone. :)

sounds like bagpipes... badass...

Either he was joking, or that's his overtone for their version of 'The Lion Sleeps Tonight'. :P

Where did you learn Tuvan throat-singing?

Fav pt start 3:28

Hahaha "friends don't let friends take videos in portrait mode"

Kevin plays the cello like Justin King plays the guitar! :)

It's actually all in the tongue! There are lesson for it on youtube. ^.^

Avi can do what is called "throat singing" or "overtone singing."

Hao!

oh come on. no hate in this video, please

Listen to the upper overtones. It almost sounds like whistling. This video's sound doesn't really capture it.

Lol @ Rooney Dunx: That's exactly what I meant!

You know, I bet if I asked God why he let Kevin into this world he would respond, "to show off" lol 😂

how to do it?

Tuvan throat singing

I just heard Cory Monteith died. This was the only thing I wanted to hear after that. Thanks Kevin.

*bass You have OBVIOUSLY never heard him sing. He sings in bass.

They cant be human.....

I meant Avi could also multitask

Hilarious - I So Thought The Girl On The Left Heard You & Was Going To Delete The Video She Was Recording & Was Going To Change The Orientation .... But Nah - She Didn't !

ooooo... :p

2:40

i don't get how that's "the lion sleeps tonight"

avi marry me T_T !!

Avi?

what is avi doing??

Heeeey she is calling my name tho

May be K.O. is the only exception... =D

Who said men can't multitask??!!

I can be done by anybody with practice.

WHERE THE HELL IS JULIO?!?!?

Throat Music man!!!
