Greatest Rock Drummers


Given the subject line many names come to mind such as  Ginger Baker, Keith Moon, Phil Collins and Carl Palmer but, is Neil Peart the greatest rock drummer of all time?

The question remains: what makes a drummer a "Rock" one? Coliauta and Weckl are incredible drummers (maybe the two best, in terms of pure technical ability), but I consider them Jazz musicians, not Rock.
audiolabyrinth, I agree, most of the posters have not heard Mike Portnoy. He can do more with his feet than most of the posted drummers can do with their hands. Neal is good but pretty basic. Listen to some older Dream Theater with Mike and then listen to some Rush songs: Rush songs are basic in nature. Dream Theater changes tempo all the time and the drum rifts are complex in nature. Ian with Deep Purple is also very good and Bohnam was excellent. For posters that indicate Ringo and Charlie are good drummers don’t know what a good drummer is. I could teach somebody to play a Beatles song or a Rolling Stones song in very little time. It is very hard to duplicate Mike Portnoy even with many years experience 
There is a myth that states that when asked if Ringo was the best drummer in the world, John Lennon laughed and said he's not even the best drummer in the Beatles.

Portnoy is amazing - so much so that he's had a hard time landing a gig with other players of his caliber and has been doing some pretty mundane stuff.
