I wish I could find a live video of it but I've always felt that the single best drumming I have ever heard is by Ralph Humphrey on Frank Zappa's Over-night Sensation album - specifically the song "Camarillo Brillo". Seriously, just like the whole song the guy is ripping it up. Definitely a lot of really talented people out there though and some great videos in this thread.
For those of you unfamiliar with Zappa - here is a link to Camarillo Brillo. The sound seems a bit off in this video, but what can you really expect from youtube.
