I agree the Neil Pert is probably at the top, but I want to add Nick Mason, the late Jeff Pocaro was awesome too. Carl Palmer is also at the top of this list as mentioned as is Ginger Baker, Stuart Copeland, Bill Bruford, Michael Shrieve...the list goes on. Really hard to pick one as the end all be all. Going back a number of years some of the studio drummers were good as well, Jim Keltner and Jim Gordon did a lot great work that wasn't really acknowledged.
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?
