Attila Csihar and Morten Iversen ("Teloch") have since replaced Kristiansen and Eriksen, respectively. Surviving former members Jan Axel Blomberg ("Hellhammer"), Jørn Stubberud ("Necrobutcher") and Sven Erik Kristiansen ("Maniac") reformed two years later with Rune Eriksen ("Blasphemer") replacing Aarseth. Mayhem disbanded after Aarseth's murder, shortly before the release of their debut album, De Mysteriis Dom Sathanas, regarded as a classic of the black metal genre. The group released their Pure Fucking Armageddon demo and Deathcrush EP that were highly influential to the development of the "second wave" of scandinavian black metal, and amassed a loyal following through sporadic and notorious live performances, attracting further attention through their ties to the string of Norwegian church burnings and the incidents of violence surrounding them. Mayhem's early career was highly controversial, primarily due to their notorious live performances, the 1991 suicide of vocalist Per Yngve Ohlin ("Dead") and the 1993 murder of guitarist Øystein Aarseth ("Euronymous") by former member Varg Vikernes ("Count Grishnackh") of Burzum. They were one of the founders of the Norwegian black metal scene and their music has strongly influenced the black metal genre. 1) Mayhem is a Norwegian black metal band formed in 1984 in Oslo, Norway.
