Guys,
OK, three others were named. I don't like Smashing Pumpkins, but I do have one of Chamberlain's solo albums, and Jon Teodore is indeed a unique drummer. So we're up to what, 4 now?
In jazz, yeah, Brian Blade has a sound, and Johnathan Blake too. But again, those are few and far between. Back then, jazz drummers had a much more pronounced, unique playing styles, even among the more electrified jazz/fusion style... Or wouldn't you know how to distinguish between a Cobham or a Mouzon?
My point is that, like guitarrists, I think drummers gave up trying to have a distinct signature, in playing and recording styles. Back then, you KNEW it was Bonham, same as you KNEW it was Iommi on guitar.
And that has NOTHING to do with appealing to audiophile sensibilites. Regular rock fans appreciate a distinct sound signature in their favorite musicians, and that's why a lot of the greats of 60s/70s are...erm... greats! Not only they record music people appreciated, they did it with a style of their own.
Now, it's hard to find a musician that actually cares how their instrument sound, or even putting their own unique signature on the recording. Most are happy to just have something out there.
