the best drummers in modern rock and roll are
jimmy chamberlin - smashing pumpkins, zwan, etc
danny carrey - tool
those two guys have it all, speed, creativity, feel, talent, and an eerie sense of what beat is right for the song.
if you've ever seen jimmy live, you know he's not human. all those quick fills and accents and rolls? HE DOES THEM WITH ONE HAND. not only that, he does them twice as fast as on the records, because the pumpkins played really fast live. honestly, if you listen closely you realize he is playing some of the most dense beats in rock and roll, but he does it so effortlessly and so subtely that you wouldn't notice unless you were looking for it. when you see him live, it doesn't even look like he's trying hard because he's so fast and his wrists are so strong that he doesn't need to flail his arms around to get power.
and danny carey, well his drumming just speaks for itself.
lars ulrich is a skilled drummer but a terrible musician. his feel for the instrument is awful. if you want to listen to the same drumming style done correctly, listen to Andrew WK's lastest album, the drumming is fantastic.
dave grohl is great just for the energy he puts into his playing, but he's not the best.
