Cobain was underweight and of below average height (5'7 tall and 130 pounds), and (usually) wore his hair long with a 'designer stubble' style of beard. His hair however was also dyed numerous exotic colours, such as bright red and blue, at various times.
It can be argued that part of Cobain's continuing legacy is his rough good looks and 'everyman' quality. He was an outspoken critic of homophobia, sexism, racism etc., even going as far as to say "If you are either a racist, sexist, or in any other way an asshole, don't buy our albums. I don't want your money. Don't love me because I hate you."
Kurt Cobain died after battling lifelong depression on April 4th, 1994 of a self-inflicted gunshot wound to the head. He was 27. His suicide note was addressed to "Boddah", an imaginary childhood friend his parents invented for him to help him cope with his uncle being drafted during the Vietnam War.
Girl 2: Crank it up, I wanna hear Kurt sing. =D
Most people would like to talk about his death, if he was killed, if he committed suicide, etc, and this very fact alone might have made him a legend to many people. But to me, he's a legend because he made great influential music. Music that rock wouldn't survive without. Nirvana is the core and heart of the rock body. Embrace him, not his death.
