Revolver Magazine has put together a special issue surrounding the “Big Four” thrash bands, in order to celebrate the recent shows Metallica, MEGADETH, Anthrax and Slayer have been playing together. At the Sofia, Bulgaria show, the bands all came together onstage to perform a cover of Diamond Head’s “Am I Evil?” and on Revolver’s website, some of the players look back at the rehearsals that led up to that cover.

Ellefson commented, “It was great. As soon as I walked into the rehearsal room, [Metallica bassist] Robert Trujillo was like, “Hey, Junior, glad you’re here.” And he hands me the bass. He was like, “Here, you jam.” And I was like, OK, I guess I’m the bass player in this little endeavor right now. So I played, and that was fun for me to sit there and be that guy. Lars was the drummer of course, and so we were kinda hanging by each other, because he and I have gotten along really well over the years. And I look and I see [MEGADETH guitarist Chris] Broderick, [Metallica vocalist-guitarist James] Hetfield, [Dave] Mustaine, Scott Ian, [Anthrax frontman] Joey Belladonna, and everybody standing there. And it was one of those classic moments. I remember as I kid, I would flip through a guitar magazine and see a classic photo of Jimmy Page, Paul McCartney, and, like, Keith Richards all being in the same room together. To me, that was our moment. It was just these guys who have never all stood in a room together before. And especially with their guitars on, creatively working on something together.”
