Nirvana is marking the 30th anniversary of In Utero, their third and final studio album, with a big reissue release.

-an 8LP super deluxe set

The super deluxe sets will undoubtedly intrigue Nirvana fans. These sets will feature 72 tracks, with 53 of them being previously unreleased. The unreleased tracks feature two full In Utero-era concerts: A 1993 show recorded in Los Angeles and a 1994 show recorded in Seattle, which was Nirvana’s final performance in their hometown.

In addition to the unreleased tracks, the In Utero super deluxe box sets also feature the following:

-a 48-page hardcover book with unreleased photos

-four cloth sticky tour backstage passes: Press, Photo, After Show, and Local Crew.

In Utero remains beloved among rock fans. When it was first released, David Fricke wrote in a review for Rolling Stone, “‘In Utero’ is a lot of things—brilliant, corrosive, enraged and thoughtful, most of them all at once. But more than anything, it’s a triumph of the will.”

The In Utero reissue is available for pre-order here.
