You people are contradicting his technique into something bad, you're taking every thing that he's good at and making it seem like it's some terrible pathetic thing. He had amazing technique, he didn't sit and beat the crap out of the drums to play loud, he actually knew how to control the heads to make them play loud. He started Heavy Rock drumming, and you people just seem to think that he's some little small detail of drumming and that he's not good. I don't care what any of you say, but to me he's still amazing with that right foot and he's still gonna be my drumming idle.
Oh yeah, and Plant once said that he was good at keeping drumming simple and keeping the beat. Isn't that what drummers are supposed to do hold the beat, tempo, and groove with the song? He did an amazing job of that, stop nitpicking.
