Peace Sells (Live At The Phantasy Theatre, 1987)
Label: Capitol Records
Dave Mustaine single-handedly crushes the opposition with this, Megadeth's second record. The group's trademark complexity runs from top to bottom -- from the maze-like riffing and breakneck changes to the beyond-Metal subject matter of the songs. This one broke open the whole Thrash genre and its power has done anything but weaken in the ten-plus years since its release.
