double sax and clarinet

Whoa, that is awesome! This would be almost impossible with two double-reed instruments, or one single-reed and one double-reed.

two double reeds is actually a bit easier- there's more room! There was a famous oboe player back in the day who would play three oboes at the same time, can't remember his name...

Hella cool!

what is the name of this song? it is very creepy reminds of a haunted circus or a song that would come out in a japanese horror flm :)

I never gave it a name, what should I call it?

uhm... i don't know :( i'm not very good with names

Yes. You are not supposed to puff out your cheeks. However, I think in this case, embouchure technicality is less important.

You are supposed to puff out your cheeks when you are circular breathing. Notice how long I play without pausing for breath, that is because I am breathing in through my nose while puffing air out through my cheeks. There is no way to circular breathe without puffing out your cheeks. There are many tutorials here on youtube on circular breathing, check 'em out.

I was more saying the embouchure point being you are playing two instruments but yes, circular breathing does consists of puffing your cheeks. Some good work!

PRETTY SURE he's circular breathing when he puffs out his cheeks. JUST SAYIN. I think he's too good to puff out his cheeks when he plays. Nice ignorance.
