Following her tragic passing on July 23, 2011, some of the producers and musicians who worked closely with 5x Grammy Award winning artist - Amy Winehouse, among them Salaam Remi and Mark Ronson - spent time listening over the many recordings that Amy had made, before, during, and after the release of albums Frank and Back To Black. It was said by all who worked with Amy that she never sang or played a song the same way twice. It quickly became apparent to both Salaam and Mark that they had a collection of songs that deserved to be heard, a collection of songs that were a fitting testament to Amy the artist and, as importantly, Amy their friend.

Lioness: Hidden Treasures is the third album from Amy Winehouse, who is without question one of the most talented, original, and best loved artists to emerge in popular music for decades. The 12 track collection features previously unreleased tracks, alternate versions of existing classics, as well as a couple of brand new Amy compositions. Compiled by long-time musical partners Salaam Remi and Mark Ronson in close association with Amy's family, management and UK record label Island Records, Lioness: Hidden Treasures proves a fitting tribute to the artist, the talent and the woman, and serves as a reminder of Amy's extraordinary powers as a songwriter, a singer and an interpreter of classics.

A portion of the proceeds from the sales of the album will go to the
Amy Winehouse Foundation.
