Photos: Preview the Experience Music Project's Massive Nirvana Exhibit

Cobain performing with Nirvana in Cambridge, Mssachusetts, April 18, 1990. The exhibit will also feature the first guitar Cobain ever smashed onstage. "I think it's really fascinating that somebody was so excited about Nirvana in 1988, before there was ever a glimmer that they would be going anywhere, so psyched by that band that they would keep this broken guitar. It was an Evergreen student, and he held onto it and I bought it from him probably about ten years ago," McMurray says. "It really cements the fact that Nirvana is a big deal. And it's something that?I think Nirvana is one of those rare bands that is going to transcend the generations, and fifty, a hundred years from now we'll still remember them."
