Who are some fast blues or jazz piano players?

Early Andre Previn (with the trio) and some Harry Connick Jr.

Tom Waits if specifically hopped up on the music or...

Ben Folds - for the younger generation

I looked over the answers, and I'm pretty blown away that nobody has mentioned keith jarrett. He has an intuitive understanding of the piano par none. He gets piano like chopin gets piano. That said, other jazz greats include tommy flannagan, bill evans, herbie hancock, chick corea, art tatum (his technique is kinda sloppy, but he's a very interesting case, especially for someone coming from a classical background), fats waller, duke ellington, vince guaraldi. it also wouldn't hurt to listen to jazz that isn't piano focused. The biggest influence on my playing (aside from keith jarrett and Modest Moussorgsky) has been listening to the improvisations of horn players, most notably tenor sax player lester young. if you're really serious about looking into jazz, the book visions of jazz: the first century by gary giddins is absolutely wonderful.
