Dead 

Per Yngve Ohlin a.k.a Dead was a swedish black/death metal musician who was obsessed with death. He shot himself on April 8, 1991. He was 21 years old. He is still one of the best musicians to walk this earth because he popularized corpsepaint, he wrote great music, his live performances were amazing and brutal; he had a great and a unique personality, he didn't care about being popular, he was real with his musicianship.

Dead played a big part in the making of the Mayhem's album "de mysteriis dom sathanas", which is arguably one of the best black metal albums ever.
