The Experience Music Project will be hosting the "world's most extensive Nirvana exhibit" next year. Titled Nirvana: Taking Punk to the Masses runs April 16, 2011 – April 22, 2013, the event will feature memorabilia celebrating the music and history of the influential band. Bassist Krist Novoselic commted on the exhibit:

Kurt Cobain was a visionary artist who touched people all over the world. It's great that there will soon be a collection that celebrates that contribution to music and culture. There's a story with Nirvana at its center, but it's a story that also includes the many people, bands and institutions that make up a music community. The show is a celebration of Northwest music.

Some key parts of the exhibit include never-before exhibited, high school painting of two aging, Reagan-era punks in the post-apocalypse, informally known as "punk American gothic," the Teac reel-to-reel tape machine owned by Mari Earl, Cobain's aunt, on which a young Kurt recorded material for his early bands, Organized Confusion and Fecal Matter, Cobain's handwritten lyrics for Nirvana songs including "Spank Thru" and "Floyd the Barber." Numerous instruments, including pieces of the first guitar Cobain destroyed onstage (a Univox Hi-Flyer); Dave Grohl's Tama Rockstar-Pro drum kit; and Krist Novoselic's Guild acoustic bass guitar and Buck Owens American acoustic guitar used during the recording of "MTV Unplugged."
