"Buyer beware. I purchased the CD anticipating interpretive versions of his most famous pieces played by Gershwin himself. But instead, the CD consists of reproduced player piano rolls--very mechanical, no change in tempo, and just plain irritating to listen to, after the novelty of the first track wears off. I looked back at the product detail to see if I had missed the mention of "player piano versions", but found none. Big disappointment."
