I saw this guy on the train here in NYC a couple months ago, he did a ridiculously hot set with his friend on the cello or violin or some string ish. I almost had to grab the mic right there on the platform. Anyflute, I just found him on youtube: Greg Pattillo, here doing Inspector Gadget, then remix/blending into "Axel F" (the theme song from the Beverly Hills Cop soundtrack).
While receiving Greg's blessing I also found another guy, Tim Barsky, who also rocks the Flute-Beatbox:
Who says hip hop is dead? Respect the evolution ...
