1. Metallica - 'Master of Puppets'
Well, this wasn't much of a contest. Metallica's 1986 LP Master of Puppets blew the competition completely out of the water. It's no big surprise. The disc captured Metallica at the height of their powers. It's their final work with bassist Cliff Burton, and many feel it's their last truly flawless record. Picking the best song is a difficult task, but the title track is an epic that never gets old, even though they've pretty much played it at every concert during the past three decades. Much like Black Sabbath's early work, the album inspired musicians all over the world to first pick up their instruments. Though it's a monumental disc, it took a few years for critics to fully appreciate it. Metallica played the album straight through on a European tour in 2006 to celebrate its 20th anniversary.
