just to add about Dead and Mayhem
Dead was a Swede previously from the band
Morbid. He was strongly fascinated (as his stage name indicates) by death, decay, and darkness. Even
Euronymous described
Dead as mentally unstable and possibly schizophrenic.
Dead became well known for his strange behavior: he buried a set of clothes for months underground so that he could wear decaying rags onstage at
Mayhem shows. He also kept a rotting raven in a plastic bag so that he could "inhale the scent of death" before each song he performed.
In 1991,
Dead committed suicide by means of a shotgun blast to the head (he had also slit his wrists several times). The bullets which he used had been sent to him by
Count Grishnackh (the sole member of the black metal band
Burzum and the man who later killed
Euronymous), who apparently thought this was cool but denied having any advance knowledge of the suicide.
Dead's body was discovered, along with a suicide note reading "Excuse all the blood", in a back room of the band's house (this statement in the note is ironic considering he was often accused of being humorless).
Euronymous quickly took pictures (which later appeared in the booklets for several subsequent Mayhem releases and other bands' materials) of the bloody scene using a polaroid camera. Persistent rumors assert that he then cooked and ate pieces of
Dead's brain, and that fragments of
Dead's skull were collected and forged into necklaces by both
Euronymous and
Hellhammer
