I can't believe this guy was in Modern Drummer. He has the worst technique of any professional drummer I've ever seen. Of course there are people like Barker who break cymbals, but Aaron's horrible technique will eventually end his career in percussion. An important message to everyone here who looks up to this guy: DO NOT PLAY YOUR DRUMS LIKE AARON GILLESPIE. YOU WILL PERMANENTLY DAMAGE YOUR BODY. This guy should not be looked up to, respected, or even given a thread. There's no excuse for playing this badly.
I'm not posting it, but there's a pretty gory video of the temporary damage he's done to his body on Youtube.
