Alex van Halen, keith moon, and not really a rock guy but one of the best percussion artists I've ever seen is Dario Rossi, he's a street performer that actually uses trash metal and junk to make techno (yeah I know) beats. Dude straight up beat on buckets and metal pipes and gongs for 20 or 30 minutes making an awesome beat the whole time, I have serious respect for that. Check it out sometime, i dont usually get interested in that but i became hypnotized by the act...
