The album will be released as a remastered CD, vinyl and digital release, a two-disc set featuring rarities, live cuts, B-sides and demo recordings, and a “super deluxe” four-CD/one-DVD limited edition that will include an alternate mix of the album, a 90-page book and a CD/DVD of Nirvana’s 1991 Halloween gig in Seattle.

A special art, photo and memorabilia exhibition celebrating the anniversary will take place next month in London, England.

Novoselic will join local musicians at a Seattle concert this fall to mark the 20th anniversary of “Nevermind”. According to RollingStone.com, the event will take place on September 20 in the Sky Church venue at the Experience Music Project. It will double as a benefit for Seattle music industry figure Susie Tennant, who was recently diagnosed with cancer.

The album will be played from front to back by different groups, although Novoselic tweeted that he himself will be performing just one song with the Presidents of The United States of America. Other musicians scheduled to appear include current and former members of Seattle acts like the Fastbacks, The Screaming Trees, Vaporland and others. Former Nirvana drummer Dave Grohl will not be able to attend, as his band Foo Fighters performs in Cleveland that same night.
