Lead singer of the grunge band Nirvana (together with Dave Grohl and [Krist Novoselic]?). He was married to Courtney Love (singer/guitarist with the band Hole), with whom he had a daughter Francis Bean Cobain. He had a pet lop-eared rabbit.
He commited suicide in 1994, aged 27, shooting himself in the face with a shotgun. His tragic death inspired a few copycat suicides and a host of conspiracy theories regarding his death.
Cobain is often credited with almost singlehandedly creating the Grunge Music movement.
