good jazz piano

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
