Two of fiction's most brutally metal and/or totally righteous musical groups are on course for audio animosity...but this is no ordinary battle of the bands. The winners of this guitar squealing showdown will determine the course of human history, as their music leads the planet Earth to its salvation, or its downfall. That most excellent duo of Bill S. Preston, Esquire, and Ted "Theodore" Logan, along with their Wyld Stallyn bandmates (princesses, robots, Martians, and Death) seek to usher the human race into a day-glo surfer-speaking utopia. But Nathan Explosion, William Murderface, Toki Wartooth, Skwisgaar Skwigelf, and Pickles, the force of ultimate destruction collectively known as Dethklok, are exercising their dark influence to bring humanity to its knees in the wake of the Metalocalypse! Which band will, quite literally, rule the world? What bizarre time travel-related argument have Sup Nerds guest hosts Spike and Taulbee concocted (allegedly with the aid of cocaine)? Can Miles successfully alienate the entire state of Florida? And isn't anybody going to do the Toki voice?
