Covering rock and roll, alternative rock, rockabilly, Motown, and garage rock, entries feature such artists as Janis Joplin, Ritchie Valens, and Frank Zappa.
I did enjoy the encyclopedia format of this book, it was fun to flip through looking up favorite bands. The main problem is that it only gives general info on more well-known acts. This might be a 5 star book for someone who doesn't know much about music, but as a buff I didn't learn anything I didn't already know.
