Dethklok is the world's most violent metal band. In fact, the band's music is so savage, fans have to sign "pain waivers" just to enter the concert venue, or suffer the wrath of the Klokateers, the band's loyal servants. Nathan Explosion (vocals), Skwisgaar Skwigelf (lead guitar), Toki Wartooth (rhythm guitar), Pickles (drums) and William Murderface (bass) inspire a wave of death and destruction wherever they play. As part of a 30-city tour, Dethklok will be bringing their unique brand of mayhem to the House of Blues, with a little help from their death metal friends Machine Head, All That Remains and Black Dahlia Murder. It promises to be the perfect night to celebrate the upcoming Mayan Armageddon.
