Query: Decent overview of Sumac's career, but could be done better.

I enjoy Yma Sumac - my mother used to tell me stories when I was a kid about how a lot of people didn't believe that Yma Sumac's voice was real, that it must be faked somehow. But the reality is, this woman had a set of pipes that will knock your socks off.This collection of songs takes a little stroll through some of Sumac's best work, but doesn't quite hit all of the high points. For example, "Gopher," made famous by films and television commercials, is not a part of this collection, which is disappointing. However, it's a good, broad sampling of her work, showing her range of style and talent.
