As a drummer, I agree he was for the time. However, Ginger Baker of Cream started the duel bass drum hard hitting rifts and fills (think Sunshine of Your Love). Until Baker, that sound didn't exist with all the British invasion bands. Bonham perfected it.
Baker is a jerk, but he really did change rock drumming. As great as Moonie was, I think Baker turned out to be a much bigger influence. He truly is a jazz drummer in a rock band.
100% true. Ginger Baker was way underrated and continued to be ignored historically.
