There’s been a lot of observance lately of Nirvana’s genre-defining album Nevermind turning 20 years old. The Experience Music Project is highlighting the anniversary September 20-25 with a celebration featuring a benefit concert, world premiere film screening, panel discussions and more.

The museum has been hosting a show (Nirvana: Taking Punk to the Masses) featuring an extensive exhibition of memorabilia celebrating the music and history of the Northwest grunge band.

The main event at EMP on September 20, Nevermind Live, features a lineup of Seattle bands from the grunge era and today performing every song in the iconic album. Performers include Krist Novoselic, The Fastbacks, Visqueen, Champagne Champagne, Tacocat, Crypts, Vendetta Red, The Long Winters, Ravenna Woods, Vaporland (ex-Love Battery, the Fluid, TAD), Valis (ex-Screaming Trees), Campfire OK, and others.

The show is at 9 p.m. in the Sky Church at EMP at Seattle Center. Tickets are $15 for EMP members and $20 general admission at BrownPaperTickets.com. The show will benefit longtime Seattle music industry maven Susie Tennant, recently diagnosed with cancer.
