Amy Winehouse's landmark 2006 album Back to Black will be reissued in special vinyl and CD formats on October 23 to mark its 20th anniversary, record label Universal Music announced on Tuesday.
The anniversary edition will feature the original tracklist alongside four previously unreleased demos and four rare B-sides.
It will also include a live performance by Winehouse at the Paradiso concert hall in Amsterdam from February 2007, recorded during her Back to Black tour and never before released on vinyl or streaming services.
The reissue is scheduled to arrive four days ahead of the anniversary of the original release date, which took place on October 27, 2006.
Special Formats and Unseen Material
The special anniversary packages will be offered with an alternative album cover and colored vinyl options, including an exclusive edition featuring animated moving images of Winehouse.

The physical formats include previously unseen photographs by Mischa Richter and Alex Lake, who photographed the original album artwork, as well as handwritten notes by Winehouse and producer Mark Ronson.
In a statement published by Universal, Ronson said that it was incredible that six songs created during a burst of musical passion still meant so much to so many people two decades later.
Background and Musical Legacy
Winehouse, an English singer and songwriter acclaimed for her soul, rhythm and blues, and jazz style, achieved international stardom with Back to Black before her death in July 2011 at the age of 27.
Ronson co-produced the album, which established Winehouse as one of the defining voices of her generation and became a massive commercial and critical triumph.
Back to Black remains one of the most celebrated records in modern music history, selling more than 4.5 million copies in the United Kingdom alone, earning widespread critical acclaim, and winning five Grammy Awards.
The Paradiso, where the 2007 live track was recorded, is a renowned music venue in Amsterdam housed in a converted 19th-century church building that has hosted major international acts for decades.
