I'd put Dave Grohl in that list. I remember seeing him on Letterman a few years back after he'd won some award for "guitarist of the year" or something. He turns to Letterman and says, "that's funny, b/c, you know, I'm a drummer." I'd also add Jon Fishman, but it's hard to convince others that he's as good as he is. I'd say Grohl is an excellent musician before I'd say he's an excellent drummer. The fact that he's great a drums, vocals, and guitar make him an excellent overall musician. As far as what he has contributed to the modern drumming community, i'm not sure. Definitely not as much as Carey or Chamberlain. While I do recognize that Fishman is a great drummer from both things i've read and his drumming that i've heard, you don't have to convince me of that, I just don't care for Phish. my favorite drummers list is, in order: Bonham, Peart, Danny Carey, Keith Moon, Jimmy Chamberlain, Alex Van Halen, and Matt Cameron.
