I'm surprised that no one has mentioned, Gershwin plays Gershwin, the Piano Rolls on Elektra/Nonesuch. Fabulous piano playing by the composer himself. The Rhapsody in Blue is a revelation. I think Mr. Tilson Thomas is going to have to re-think how it is played (I also have his Columbia cd). No dreamy eyed or studied performance this, it's rollicking kick ass jazz and frankly the way the piece should be played. Now if we can do something with an American orchestra, along the lines of what RCA did years ago to the Grieg piano concerto with a Percy Grainger piano roll and an Australian orchestra, we just might have the ultimate RiB. In a pinch my vinyl copy of Manhattan (with Gary Graffman and the NYP/Mehta will have to do). BTW does anybody know of a real good interpretation of the Gershwin Piano Concerto?
