No fear...I is here!
Great drummers aren't merely bangers. They have to know how to finesse and help raise the music to a higher leve.
Having said that...here are my thoughts.
John Bonham
Neil Peart
Mike Portnoy
Buddy Rich
Steve Gadd
Thomas Lang
Some lesser knowns but still among the best:
Dom Famularo
Kim Plainfield
Jason Bittner (of Shadows Fall - hear him solo)
You been learned now. School's out. Peace.
