Query: Lenny Can Tickle The Ivories Too

While I love Leonard Bernstein as a conductor, I have to admit that my first (and only prior) experience with him as a pianist left a lot to be desired. I purchased the "Bernstein Century" recording of Gershwin's "Rhapsody in Blue," a performance that did not do much for me. Even though my criticisms had mostly to do with the tempo of the piece, it left such a bad taste in my mouth that I had serious doubts when it came to Lenny playing piano. But then I came across this title, and because of Amazon's editorial review and its selection as an "essential recording," I decided to get over myself and purchase this CD. Well, I couldn't have asked for a better performance of Mozart's 15th and 17th Piano Concertos than the ones L.B. has provided here. It's hard to believe that this is the first time this material has been released on CD, because it is one of his truly great recordings. I now recommend Bernstein both as a conductor and performer without reservation.
