Keith Moon hands down is the best rock drummer of all time. If you think otherwise, you just don't know rock n roll.
I would put Bonham in second and then there is a big drop-off in talent. I think Peart, Alex Van Halen and Mitch Mitchell round out the top 5.
One drummer that is in the top 10 and I did not even see mentioned in this list is Sib Hashan of Boston. Man could he keep a beat and some of the best hands around.
I guess everybody is entitled to their opinion, but there is no doubt that Moonie set the bar higher than anyone and made the drums a listened to instrument and not just a backing beat.
It is a shame that we did not get to listen to him longer than his short life.
