Headbangers, rejoice, because this fantastically illustrated encyclopedia includes all things metal, from influential bands such as Led Zeppelin, Blue Cheer, Iron Butterfly, KISS, and Queen, to Mötley Crüe, Black Sabbath (before ozzy became a family sitcom star), Deep Purple, Twisted Sister, and Aerosmith, right up to Jane's Addiction, Las Cruces, Limp Bizkit, and today's most extreme death metal bands.
