OK, Like 8Mile, I put Roy at the top for his contributions, not just virtuosity. But the rest of the list is tough. Here's the "Easy" list, and I thoroughly agree with 8Mile's description:
1) Roy Haynes
2) Jack DeJohnette
3) Jimmy Cobb
But I would also interchange any of the other two with:
Andrew Cyrille- scary intensity at the highest playing level, has played with Cecil Taylor, Coltrane and Albert Ayler.
Joe Chambers- has played with Miles, Andrew Hill, Joe Henderson and Max Roach's M'Boom plus many other greats. He has a great, crisp, authoritative sound. Very underrated.
Louis Hayes. I mainly know his playing with McCoy Tyner, but he's right up there with the best.
Ben Riley- Anything with Monk.
Charlie Persip- Killer playing with Rahsaan Roland Kirk and Great brush playing.
Ronald Shannon Jackson- If you can find his record "Pulse" anywhere, buy it. Also stuff with Ornette Coleman's Prime Time, his Decoding Society stuff, anything with Cecil Taylor.
I'm starting to run out of descriptive steam. But each one of these players is a university of study:
Billy Hart, Smitty Smith, Jeff Hamilton, Idris Muhammad, Bob Gullotti, Cleve Pozar, Bob Moses, Johnny Vidacovich, Butch Miles, Peter Erskine, Arghh! I hate these lists! I know I'm leaving a bunch of Greats out!
