I'm a bass player so my take is that good drummers are about the song, not the instrument. My top five are:
Al Jackson (Booker T. & The M.G.'s) Only do a fill when the SONG calls for it, not just because it's been four measures since you played a fill.
Ginger Baker (Cream, but so much more!!) Yeah, he's sorta the opposite of Al Jackson to some people, but he's simply the most MUSICAL drummer ever. His trio album with Charlie Hadden and Bill Frissell is a treasure. He's busy sure, but that's not the point. The point is that he's always LISTENING to the rest of the band and having a musical discussion with them, not just playing a steady background- he's actively involved with the music.
Steve Gadd Sure he's responsible for all those clowns who tried to nail "50 Ways To Leave Your Lover", but he's so perfect for so many different music. He again is a drummer who's listening to all the music and working to make it all sound good, not just the drum part. Check out Clapton's "One More Car, One More Rider" live DVD for some wonderful drumming from Gadd.
Hal Blaine He's the one who made all those session tracks come alive. Huge impact on how pop music sounds
Russ Kunkle Just because a huge part of my music education included listening to Jackson Browne, Carol King, James Taylor, Crosby & Nash, etc. for whom The Section (Kunkle, Leland Sklar on bass, Danny Kortchmar on guitar, and Craig Doerge on keys) were the session and road band backing them. It's in my DNA now.
I also gotta respect Ringo Starr. I had a buddy who when auditioning drummers would always ask them "Is Ringo a genius or an idiot?". Invariably the drummers who really understood playing drums in a gigging band never answered "idiot" (actually the best answer was they guy who said "Well, he was a genius for really understanding what those songs needed and having the restraint to never assert himself in it, but he was an idiot for never really trying to be a better physical drummer."
