In no particular order:
Keith Moon--did anyone really play drums any better? Watch videos him play and it looks like he's totally out of beat, and yet it worked. He did rhythms with one hand that some people can't do with two.
John Bonham--the king of the heavy metal beat.
Charlie Watts--I'm including him mainly b/c so many drummers site him as an influence. He is not flashy, but he never misses a beat and seems to be a great fundamental drummer. it's not all about flash, it's about keeping the beat.
Mickey Hart/Bill Kreutzman (of the Grateful Dead)---I'm cheating a little by putting them together, but the two of them do things and make sounds with the drums that few others else have done, at least in the rock and roll world.
Neal Peart--sometimes he sounds like two guys playing.
Honorable mention: Lars Ulrich (great talent), Dave Grohl (he basically plays one style, but does it well--could fill in for Bonham in Zeppelin ever reforms), Jon Fishman (from Phish--the guy can play any type of music thrown at him, he sounds like two people playing also), Tommy Lee (yeah, he's nuts and makes internet videos, but he nails the tubs), and the guys from Rusted Root (there's three of them and they each play different types of percussion, some only with their hands---wild stuff).
There's probably others I'm forgetting...
Bagster, you've got to come up with more than 4, you saw 4 drummers this week alone! ;-)
