Try to find a better recording.
There's no substitute for Gerswhin playing Rhapsody in Blue. His energy and enthusiasm are unparallel by other artists, and after you hear his solo version, an orchestra only seems to get in the way. However, this recording is far inferior to others -- the piano playing is uneven and sloppy throughout. When you know how well Gershwin can play this piece, you can only find this recording to be a disappointment. I wish I could recommend others, but I threw this one into the trash can and kept my scratchy recording from the 1970's vinyl. Hopefully there are better ones on emusic.
