more about Mayhem.. the lunatic Black Metal band 
these guys belong in a padded cell 
Formed around 1985 by Necrobutcher and guitarist Euronymous (born
Oystein Aarseth), Mayhem was the first death metal band from Norway
to make much of an impact in their homeland, which in the early
'90s developed a burgeoning underground scene rife with violent,
sometimes anti-Christian activity -- as evidenced by Mayhem's
non-musical history.
Drummer Hellhammer, who at one time worked in a mental hospital, is
the only remaining member of the band's prime-period lineup.
Lead vocalist Dead committed suicide in 1991 (two years after
joining the band) by shooting himself in the head; Hellhammer made
a necklace using some of his skull fragments, and Euronymous
reportedly cooked and ate pieces of Dead's brain.
Euronymous, in turn, was stabbed to death while in his underwear on
August 10, 1993, by the band's bass player, Count Grishnackh (born
Christian Vikernes). Grishnackh's alleged motive was jealousy over
the fact that Euronymous had a more evil reputation; he inflicted
23 separate wounds, it was also rumored, so as to outdo rival band
Emperor's drummer, Faust, who was convicted in the stabbing death
of a homosexual acquaintance.
When police arrested Grishnackh, they found over 150 kg of stolen
dynamite in his house, complete with a plan to blow up a large
church on a religious holiday. Grishnackh went on to pursue his
electronic-influenced project Burzum while in prison; meanwhile,
Euronymous' parents requested that his bass tracks be erased from
Mayhem's 1994 album, De Mysteriis Dom Sathanas, (which featured
session vocalist Attila Csihar).
Still, thanks to growing worldwide interest in Norwegian death
metal, Mayhem product has continued to appear on the shelves into
the next century. Hellhammer also put together a new Mayhem lineup,
which has toured sporadically.
During one such tour in 2003, a concert-goer in Norway received a
fractured skull as a sheep head flew from the stage while band
member Blasphemer was cutting the head away from the torso.
