Beatbox+harmonica == Gg Check this out.

Wow this guy is crazy to the max, Beatbox is so easy to do, I can do it too, but combine it while playing a harmonica for so long like him(So much air), WOW thats like impossible for me. If any of you can can do it say so cause I sure as hell can't.
I had to dig for that video so much so please appreciate it and don't say that you can hear that at a local club.

And for anyone who doesn't know what a harmonica is, here's a quick definition: a small, hand-held wind instrument on which tones are produced by exhaling and inhaling into recessed air slots.
