I've played the flute and picc for 15 years now and have participated in my fair share of chamber ensembles, duets and trios ... but I gotta say, we've taken a break and goofed off a bit... but we've never let loose and done anything like this before:
Of course, these guys aren't goofing off. It's improvisation!
I respect this. Because I seriously lack the rhythm and skill to simultaneously play and beatbox.
I wonder if I know any cellists and bassists that are badass enough to be guinea pigs... we're all about improving our musicianship, I'll use the excuse that beatboxing improves dexterity on double and triple tonguing riffs.
