Greatest Rock Drummers

There is never a single "best" in any art form. Both Hendrix and Segovia are great, but they can't be compared to each other. The same is true of painters, composers, writers, etc. It's not a foot race where one will have the best time - these people are going to different finish lines!

But there are some great drummers who haven't been mentioned here:

Clive Bunker (Jethro Tull)
Danny Seraphine (Chicago)
Terry Bozzio (Zappa)
Colaiuta (mentioned already, I know)

And that's just rock. We won't even get into jazz. But the same holds true - there is no single "best" in art. 

Did anyone mention Michael Shrieve? He was just a pup at Woodstock and earned his post as the drummer for Santana because of this performance.....

I just saw Keith Carlock playing with Steely Dan last night in Dallas. It was the finest drum kit performance I have seen live that wasn't straight ahead jazz. His Aja solo was terrific and his own. It paid homage to Steve Gadd without sounding like Gadd. Carlock is 47 years old. Worth seeing if you get the chance.  

@astewart8944 - How was the Steely Dan show overall, without Becker? I saw them on their tour 2 years ago and I thought it was fantastic. They will be here again this summer. Just wondering if I should go see the show again.

@reubent SD's band was the best group of musicians I have seen in a live performance (again jazz excepted). Fagen's voice is struggling; but the band and the backup singers so strong that it wasn't that big of a deal. "Ready" Freddy Cunningham played bass all night with the exception of "Peg" when they brought out Chuck Rainey, who did great. He lives in Dallas--I doubt they are doing that cameo anywhere else. I recommend you see the show. Harrington killed all the guitar parts; it is hard to be too superlative about his chops.
