This is all really subjective, and a little narrow. For instance, there is no funk category. Some of the best drummers I've ever heard come from this genre. One in particular: Dave Garibaldi. If it weren't for him, people like Dennis Chambers, Dave Weckl, and even Carter Beauford probably wouldn't have some of their current drumming vocabulary. But, it's a fun site.
By the way, did Maurice White really play the drums on EWF's All 'n All record? I thought he just sang.
