Wow. That was quite something. 0_o Those runs are amazing... I totally believe you now about the chords too.

To this day, I've never seen anyone with a left hand like Art Tatum. I play piano, but I'm no piano player if that makes sense. I'm more guitar and bass, but piano helps with songwriting. As someone who plays, I know you listen to piano differently than most. Art Tatum is one of the scariest piano players I've ever heard because I know how to listen to him. Another one people seem to forget could play the shit out of a piano was Nat King Cole: http://youtu.be/mUEcIw6tUkM
