Metallica, Slayer, Megadeth And Anthrax Perform 'Am I Evil?' In Sofia Members of Slayer, Megadeth and Anthrax joined Metallica on stage last night (Tuesday, June 22) in Sofia, Bulgaria to perform the Diamond Head classic "Am I Evil?" Metallica's James Hetfield, Megadeth's Dave Mustaine and Anthrax's Joey Belladonna all took turns singing, with various other bandmembers playing guitar, bass and pounding on snare drums. "After 29 years of doing this to reach this apex is just so fucking cool," tweeted Anthrax guitarist Scott Ian moments after the performance. "It was a monumental moment of epic proportions. I'm so high from the experience I can't sleep." The last time Mustaine performed with Metallica was on April 9, 1983 at the legendary Brooklyn, New York club L'Amour. He was unceremoniously fired by the band just weeks before they entered the studio to record their debut album, "Kill 'Em All", and was replaced by former Exodus axeman Kirk Hammett.
