Amy Winehouse has unreleased music.
Amy Winehouse
Unheard tapes of the late singer - who died from alcohol poisoning aged 27 in 2011 - were discovered by 'Amy' director Asif Kapdia, producer James Gay-Rees and editor Chris King during their two years researching for the documentary.
Now the movie makers are campaigning for the 'Rehab' singer's label, Universal, to release an album featuring the tracks they weren't able to squeeze in to the biopic, including an "emotive" one about her ex-husband Blake Fielder-Civil.
Chris said: "I would recommend they find a way to release some of the stuff we listened to. There's one recording where she's getting back with Blake Fielder-Civil
"It's just piano and her singing, which is such a massive emotive performance. There are songs like that and cover versions we couldn't work into the film that I'd love everybody to hear."
An album of Amy's unreleased music curated by her friend Mark Ronson, 'Lioness: Hidden Treasures', came out the same year as her death, and many fans thought it was too soon.
For this reason, James has confessed that Universal is now wary about bringing out another album.
He said: "They're trying to do things in the right taste because I think they were quite burned with Lioness."
