AN album featuring unheard material by Amy Winehouse is to be released just months after the singer's death, it has emerged.
Amy Winehouse Lioness: Hidden Treasures will help raise money for the charity set up in her name after she died in July.
The collection is said to contain original tracks as well as covers, including Winehouse's recording of jazz standard Body And Soul with Tony Bennett.
Producers Salaam Remi and Mark Ronson pulled the album together after listening back to thousands of hours of vocals by the star, it was reported.
Winehouse's father Mitch said the songs "took my breath away".
He said: "Had the family felt this album wasn't up to the standard of Amy's others, Frank and Back To Black, we'd never have agreed to release it.
"We believe it will stand as a fitting tribute to her musical legacy."
Mr Winehouse added that he had not heard one of the new songs, called Halftime, before he listened to the collection.
The new album is reportedly due for release in December, and money from each copy sold will go to the Amy Winehouse Foundation.
