IMDB.com
This is an often amusing insider look at the music business. Keitel plays a producer who is saddled with a G-rated group and is expected to make them popular with the public. There are lots of satirical in-jokes about the egos of recording stars, their managers and the people who run the studios. It has a lot of 70s nostalgia value and many of the philosophies spouted by the characters are still en vogue with the music biz today. All in all, a good job by all involved.
