Hi Frogman, thanks for the insight, I am surprised to say the least. It's funny and indeed a bit curious to me that Bernstein would disparage Gershwin's music since he recorded the Rhapsody so many times and seemed entranced with his music, maybe a bit envious of his melodic and improvisational gifts? As to why he didn't record "Concerto in F" maybe he felt he couldn't add anything to Earl Wild's numerous recordings of this piece. While Bernstein was certainly many things and an American Icon in so many ways, he certainly isn't any Earl Wild, especially regarding interpretation and virtuosity of Gershwin's works at the keyboard IMHO!
