Dethklok returns this fall with "Metalocalypse: Dethklok Dethablum II", the highly anticipated follow up that fans have been begging for. Metalocalypse, the hit Adult Swim show centers around the biggest, most metalest band in the world, Dethklok. Each episode of Season 2 features a song from the band and the best of those have been expanded to make Dethalbum II, more brutal than ever before. Prepare for an onslaught of bone-crunching Nordic riffs.
