Hold on to your hair extensions, because two of the biggest names in heavy metal come together for a truly epic rock reckoning. Old school heavy metal giants Scorpions and Megadeth rock the stage of the Oracle Arena in a maelstrom of monster metal madness.

Dubbed the “heroes of heavy metal” by Rolling Stone magazine, the Scorpions emerged from Germany’s ’70s hard rock scene, eventually morphing into one of the world’s most recognizable power metal acts. Just this year, the band was honored for its 50-plus years of rocking with inclusion in the Heavy Metal Hall of Fame. Their American counterparts Megadeth are widely considered one of the four godfathers—along with Slayer, Metallica, and Anthrax—of modern thrash … or would it be better to say one of the four horsemen of the arockalypse? Grow out your hair, throw on your leather, and scribble pointy Stussy S’s all over the margins of your steno pad, because the metalacalypse has begun.

Oct. 4, 7 p.m., tickets start at $29, Oracle Arena, 7000 Coliseum Way, Oakland, OracleArena.com.
