Buddy Rich, hands down. Vinnie Colaiuta is right up there. Mike Portnoy is durn good. Lots more...
Agreed, but there are many others... Steve Gadd can make the most complex rythms sound simple... Until you try to figure out what he played, and how to play them. Bill Bruford, master of odd times. Carl Palmer - what can you say, other than "More Cowbell!" Terry Bozzio. Neal Peart. I'm also a fan of Jerry Marotta and Manu Katché. And of course, John Bonham and Keith Moon. And Chester Thompson & Phil Collins. Wow, the longer I take, the more names get added to the list!
