Lioness: Hidden Treasures is a posthumous compilation album from Amy Winehouse, released five months after her death on December 2, 2011 via Island Records. Upon its release, longtime producer for Winehouse Salaam Remi clarified with Complex that Lioness: Hidden Treasures is not considered to be an official studio follow-up to 2006’s Back to Black, but merely a compilation of select tracks recorded throughout Winehouse’s career. He added: The Lioness is not meant to replace what Amy’s third album would have been. That album was written but only two or three tracks were recorded. But this is definitely a collection of songs that we feel needed to be heard by her fans and that also stand up to the quality of the material that she released while she was alive—you know, with her first two albums. Among the track-list are two demo versions of songs from Back to Black, multiple covers of acclaimed jazz songs, and two new songs, “Between the Cheats” and “Like Smoke,” which were both intended to appear on Winehouse’s official third studio album. The album included two singles, “Body and Soul” with Tony Bennett, and “Our Day Will Come,” which is a cover of Ruby & The Romantics' original version.
