Due out on September 27, the 20th-anniversary deluxe edition of “Nevermind” will arrive as a remastered CD and digital release, a two-disc set featuring B-sides and demo recordings, and a “super deluxe” four-CD/one-DVD limited edition that will include an alternate mix of the album by producer Butch Vig. This version will also come with a 90-page book and a CD/DVD of Nirvana’s 1991 Halloween gig in Seattle. A vinyl edition of “Nevermind” will also be released, along with separate Blu-ray and DVD versions of the Halloween 1991 show.
All but the standard CD will feature dozens of previously unreleased recordings, obscure B-sides, alternate mixes, radio sessions, studio rarities and live tracks. The new mix by Vig will be substantially different from the final album mix by Andy Wallace that was released commercially. The Halloween 1991 show is the only known Nirvana concert shot on film and has been transferred to a high-definition picture with Surround Sound.
