Have to disagree on Keith Moon. Saw him a couple of times back in the day, and the guy was electric. Yeah, they did a lot of crazy shit onstage (and off), can't talk about his technique or even if he had any, but Keith created tremendous energy, tremendous vitality. Pure rock and roll. Probably where I got my taste for high-energy music.
One other guy I would mention, Mitch Mitchell, probably not a great drummer by most standards, but again, watching him with Hendrix was so tasty! That was the right place and time for him and the results were sterling.
As for Ginger Baker, I've always felt he gave a certain monumental quality to rock, drumming that added power and depth to the music. Something monolithic about his sound. It was like tribal tom-toms, and back then we were all tribal.
