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.
Some of the best drums I have ever heard were played by Moon on Quadrophenia.
Didn't know Baker was a jerk, but I agree about his influence. It was a new sounding kit (tuning) and new fills for rock that everyone has expanded on since. Baker, Bonham, and Moon were not as technically as proficient as modern drummers. However, they came up with new beats and fills that have influenced every drummer since.
Being a former drummer, I learned from those guys to adjust the spring on my bass pedal to get one bass beat or multiple beats with my toes and/or heel action. I never had duel bass drums. I could get that double bass while I did double time rolls around the snare and toms. Interestingly, I had my hi-hat on my right side. It just felt more correct than crossing over to the left, although I could do that also.
