where i found it: i can't remember
Generally I do not understand how or why DJs have become super celebrities that play to arenas full of people. I keep seeing stuff about Skrillex and that guy that wears the mouse head and all these super DJ people, but when I listen to the music it just sounds like a boring keyboard.
The guy in this video really goes the extra mile, though. This video is pretty crappy quality and cuts between various performances without a lot of flow, but he demonstrates some genuinely good ideas. Picking a rubber band hooked up to the stylus arm is my favorite, but the way he plays along with the toy saxophone player is pretty great too.
