Mayhem was formed in 1984 by Necrobutcher with Euronymous and Manheim. After two years of rehearsals, the trio released its first demo Pure Fucking Armageddon in early 1986.[2] Shortly after its release, the group became a four-piece when Eirik "Messiah" Norheim took over vocals from Euronymous.[3] Within a year, the vocalist had been replaced by Sven Erik "Maniac" Kristiansen, who performed on the group's first EP Deathcrush.[2] Both Maniac and Manheim left shortly after the EP's release, and were briefly replaced by Vomit members Kittil Kittilsen and Torben Grue, respectively.[3]
During early 1988, Euronymous and Necrobutcher rebuilt Mayhem with the addition of new vocalist Per "Dead" Ohlin and drummer Jan Axel "Hellhammer" Blomberg.[3] The new incarnation remained stable for several years, recording several live releases, but did not issue a full-length studio album.[4] On 8 April 1991, Dead committed suicide at a house shared with Euronymous and Hellhammer.[5] Due to his death, and the guitarist's subsequent actions (including taking photos of his body, one of which was later used as the cover for a bootleg release), Necrobutcher left Mayhem.[6]
After a brief stint with Stian "Occultus" Johannsen, the band returned in late 1991 with Attila Csihar on vocals and Varg "Count Grishnackh" Vikernes on bass.[7][8] This lineup recorded Mayhem's long-awaited full-length debut De Mysteriis Dom Sathanas, which featured material written by Dead and Necrobutcher.[9] However, before it could be released, Vikernes murdered Euronymous on August 10, 1993, stabbing the guitarist 23 times after growing tensions and business disputes.[10] The group consequently disbanded, with De Mysteriis Dom Sathanas receiving a release in 1994.[11]
Since 1995
In late 1995, Mayhem was reformed with a lineup including Hellhammer, former members Maniac (vocals) and Necrobutcher (bass), and new guitarist Rune "Blasphemer" Eriksen.[9] This incarnation remained intact for almost nine years, issuing the group's second and third full-length studio albums, Grand Declaration of War and Chimera.[12] In November 2004, Maniac left the band and was replaced by another former vocalist, Attila Csihar.[13] One more album followed, Ordo Ad Chao, before Blasphemer left in August 2008 claiming that he "simply [didn't] see any future for me in the band anymore".[14]
