This is the "Am I Evil?" demo from Metallica's debut album "Kill Em All"

On the 11th track of Kill Em All, Metallica covered the song "Am I Evil?" by British heavy metal band Diamond Head. This song first appeared on Diamond Head's Lightning to the Nations album. Metallica has made the song recognizable to metal fans today when playing it live many times. The song was part of Metallica's Creeping Death cassette single and on some pressings of the Kill 'Em All album. The song appeared again in 1998 on Metallica's Garage Inc. anthology of covers, as well as on Disc 3 of the Live Shit: Binge & Purge boxed set.
