I have the drum solo that proved it to me, joey jordison overal hands and feet is one of the fastest in the drumming world. Buddy Rich is awesome, and why hasn't Mike Portnoy been mentioned, he's a beast. If anyone's been to the subliminal verses tour you'd know what im talking about. I dont think joey gets enough credit, or for those that do like him, they dont know why hes good, if you listen closely, he is so fluent and mixes it up so well, he doesnt do the common double bass beat all the time. He is so quick in using everything he has on his huge 20 piece set. And pretty much he uses double bass all the time, sometimes its quiet in the songs but its there, for me i think he is easily the best double bass drummer. Well those 3 guys Neil Pert and the guy from the who, are pretty much the greats.
