In 1991, R.E.M. propelled alternative music onto the world stage with the release of "Out of Time". A quarter of a century later, Concord Music Group is re-releasing their masterpiece in a special 25th Anniversary edition, packed with unreleased tracks and rarities. Available in three formats (2CD, 3LP and 3CD+1BluRay), all of these reissues contain the fully remastered original album, demos of every track on the album, plus demos of two tracks destined for B-sides (and not appearing on the album) as well as an unreleased song. The 3LP box set offers vinyl versions of the original album and demos. The Deluxe edition features, in addition to the previously mentioned material, recordings from a 1991 concert at Mountain Stage – a rarity, as the band did not tour to promote the album's release – a High-Resolution audio Blu-Ray disc with 5.1 Surround Sound versions of 'Out Of Time', all the music videos from the album, "Time Piece", the 1991 promotional video with studio footage and some exclusive bonuses. All these versions are accompanied by a comprehensive booklet signed by Annie Zaleski, with interviews of the four band members, as well as producers Scott Litt and John Keane.
