Probably should include Andre Previn, Liberace, Bill Evans, Thelonius Monk and Fats Waller. (If you haven't heard the recording of William Kapell playing the Khatchaturian concerto do so immediately. The bass clarinet solos will shake your universe.)

Artur Rubenstien, Marta Argerich, Daniel Barenboim, Van Cliburn, Schnabel... William Kapell.
