American Singing Groups: A History from 1940 to Today -- Jay Warner

This is a reprint and update of The Billboard Book of American Singing Groups, and it's terrific. It's an encyclopedia of just about every American singing group you can think of, and most of the entries include a discography. I love stuff like this, and I've spent hours reading the entries. Do I have any complaints? Sure. It's the "just about" above that's the catch. I mean, why include folk-era groups like Peter, Paul, and Mary and the Highwaymen but not the Kingston Trio? What's up with that? There are also some other groups that are sorely missed, but the hundreds that are included are all wonderful to read about. Doo-wop, rock, and pop are all treated extensively. If you like this sort of thing, you need this book.
