Ok, so you've been to the concert where somebody is just sitting typing on a laptop. And for all you know, they're playing a recording and checking their email. I mean, Carl Stone rocks back and forth and so you can tell he's getting his groove on, but some folks, like me, just sorta sit there and twiddle their thumbs. There's been all sorts of discussion about how to make the performance aspect more evident so the audience gets some visual stimulation. This guy has the answer. (You must watch the video [10.3 Mb]. I swear it's accessible to everyone, not just computer music geeks.) I am going to copy him.
