Metalocalypse is an American adult animated television series, created by Brendon Small and Tommy Blacha, which premiered on August 6, 2006, followed by a musical one-hour special, Metalocalypse: The Doomstar Requiem, on October 27, 2013 on Adult Swim. The television program centers on the larger-than-life melodic death metal band Dethklok, and often portrays dark and macabre content, including such subjects as violence, death, and the drawbacks of fame, with hyperbolic black comedy. The show was widely heralded as both a parody and a pastiche of heavy metal culture. The music, written by guitarist/creator Brendon Small, was credited to the band and featured in most episodes. The animation was often carefully synced to the music with the chord positions and fingering of the guitar parts shown in some detail. The show was cancelled in 2013. In 2021, Adult Swim announced a direct-to-video film has been greenlit.
