(CBS) Amy Winehouse is set to sing again.
Island Records announced Monday that it will release a new album of recordings from the late soul diva.
The posthumous collection, titled "Lioness: Hidden Treasures," will feature 12 tracks of previously unreleased songs, alternate versions of her hits and brand new tracks.
The album will include a demo version of "Wake Up Alone," a mellower version of "Valerie," a new song called "Between the Cheats" and her final studio recording, a duet of "Body & Soul" with Tony Bennett.
Her father, Mitch Winehouse, said he had never before heard another one of the tracks, "Halftime," and described the song as "just incredibly beautiful."
"If the family had felt that this album wasn't up to the standard of 'Frank' and 'Back To Black' we would never have agreed to release it and we believe it will stand as a fitting tribute to Amy's musical legacy," he said in the Island Records statement.
The album was compiled by Winehouse's longtime musical partners Mark Ronson and Salaam Remi, in collaboration with Winehouse's family, management and the record label.
According to Island Records, Ronson and Remi had spent time since the singer's death listening to the recordings, and realized 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."
This will be Winehouse's third album, following 2003's "Frank" and 2006's Grammy-winning "Back to Black." A portion of each album sold in the U.K. will go to the Amy Winehouse Foundation, which her family established after her death to help disadvantaged youth.
Winehouse was found dead in her London home on July 23, at the age of 27. Last week, a coroner ruled that the singer died from accidental alcohol poisoning when she resumed drinking after weeks of abstinence.
