Who is your favorite jazz pianist

Art Tatum

Too many great ones out there: Keith Jarrett, Brad Meldau, Enrico Pieranunzi, John Taylor, Bobo Stenson, Ray Bryant, Paul Bley, Tord Gustavsen, Jessica Williams, Bill Mays, Larry Willis, McCoy Tyner, Frank Kimbrough, John Coates .. and that's just off the top of my head.

Kenny Barron is probably the most overlooked pianist around and one of the best still living along with Keith Jarrett.

Although he is more of a keyboard player. Jordan Rudess.

Dave Gruisen is in there as well

Oscar Peterson, Lyle Mays, McCoy Tyner
