Non classical piano based music recommendaiton

The first two that come to mind is Bill Evans and Keith Jarrett.

All of Bill's work is near perfect, my favorite of Keith Jarrett is from his days with A&M Horizon, teamed up with Alice Coltrane and Charlie Haden.

Maybe too obvious to include is Duke Ellington, but the recent releases by Classic Records of his "Piano in the Background," "Piano in the Foreground," and "Jazz Party" are absolutely superb on every level.

If you get enough piano and still hungry for keyboard, there's Jimmy Smith. He's been 40 years on the Hammond organ (1954) and rocks the keyboard like nobody else :^).

Max Richter, this is very different, emotive music. Try "The Blue NOtebooks"

Some Scott Joplin fits well in every music collection. The performances by Joshua Rifkin on Nonesuch are top drawer.

And if you're willing to consider vocal with piano, the recording After the Ball with Joan Morris and William Bolcolm is infectious fun.
