good jazz piano

Brad Mehldau

Marcin Wasilewski

Bobo Stenson - Cantando is a spooky good recording. 

Julia Hulsmann

Esbjorn Svensson 

Lots of good choices on the Three Blind Mice label.  My favorite is Midnight Sugar, a studio recording by the Tsuyoshi Yamamoto Trio.  Great performance, excellent sound.

Bill Evans at the Montreux Jazz Festival.  A fine live performance that has Evans playing a bit more lightheartedly.  Recording puts you in the hall with them.

Yuko Mabuchi Plays Miles Davis.  A lovely, inspired session recorded with holographic clarity.

Andrew Hill
Randy Weston

2nd Gene Harris
Charles Brown

I absolutely love great piano players in the trio format. My favorites:
Marilyn Crispell
Russ Lossing
John Taylor 
Paul Bley 
Myra Melford
Masabumi Kikuchi (if you can get past the groaning!)
Bill Evans
Keith Jarrett
Vijay Iyer
E.S.T. (Esbjorn Svensson trio)
Brad Meldau
Marcin Wasilewski
Stefano Bollani 
Stefano Battaglia
Julia Hulsman

...there are hundreds more.  But really, if you want a treat check out Crispell's piano trio stuff on ECM
