30 years after the death of Kurt Cobain, the mystical influence of a unique group remains. Artists and critics review the reasons why the group changed the history of rock and left an even spiritual mark.

“I'm sure the way Kurt passed away has some sort of attraction for some people, but it's not a key component of the group's legacy. Even when Nirvana existed, everyone knew they would be legendary,” says journalist Michael Azerrad, author of the biography Come As You Are: The Story Of Nirvana.
