It's a tossup between Neil Peart and Jimmy Chamberlin for me.

Keith Moon
Stewart Copeland
John Bonham
Ginger Baker

I'm going to have to update my list.

Billy Cobham
Mitch Mitchell
Gavin Harrison
Martin Lopez
Derek Roddy
Blake Richardson
Sean Kinney
Eric Sandin
Tim Alexander
Brain
Danny Carrey
Dave Lombardo
Terry Bozzio
Mario Duplantier

You read my mind. Although I'd end up going for Peart.

funny you should mention Jimmy Chamberlain as I was listening to Placebo`s debut album earlier and drummer Robert Schultzberg sounds very similiar, sadly he only featured on their debut album.

Earl Palmer
Elvin Jones
Al Jackson, Jr.
Ziggy Modeliste
Levon Helm
John Bonham

My favorites:

Thomas Hedlund (Cult of Luna)
Magnus Lindberg (Cult of Luna)
David Clifford (Red Sparowes)
Aaron Harris (Isis)
Bill Kelliher (Mastodon)

John Bonham
Neil Peart
Keith Moon

arf? Brann Dailor is the drummer for Mastodon. Bill is the guitarist.

but Brann Dailor is really good. He brings more of a traditional, almost classic rock element back to Metal.

I`ve still yet to decide whether I think Mastodon to be a classic metal band or just a good one, but one thing for certain and is as you say, the group have a classic rock element that they put into their sound, especially through the jazzy style drumming of Brann Dailor.
