Holy crap, this dude kicks ass. His name is BI33SON. Not sure how to pronounce it but that's his name.
Anyway, play the video.
You'll notice he's mixing with four virtual decks via Traktor — a feat not to be attempted unless you have your shit together in a big way. And check out his macbook... instead of the Apple icon, he has his name on the front. I think he did it with bright white printer paper and a blacklight; at least that's what they're saying on the boards. Damn!
