Previously unseen live footage of Amy Winehouse emerges ahead of new documentary Back To Black

The clip features in a new documentary about the singer's Back To Black album.

Previously unseen live footage of Amy Winehouse has been posted online ahead of the release of a new documentary about the star.

The documentary, called Back To Black, is released on November 2 and explores the making of Amy's seminal second album through interviews with producers Mark Ronson and Saleem Remi. 

Amy's famous gig at London's Riverside Studios - a private show that took place in 2008 on the night she won five Grammys - is included as a bonus feature on the DVD. 

Footage of the singer's performance of Love Is A Losing Game from the show has been posted online. Watch below: 

Back To Black is one of the Top 10 biggest studio albums of all-time, with 3.93 million sales to date. Check out the full list with sales figures here.

Amy's family recently announced plans to make a biopic about her life, reportedly directed by Alison Owen, whose credits include Suffragette and Me Before You. 

It was also recently announced that a new immersive concert experience featuring a hologram of Amy will begin in late 2019. The concert is being put together by Base Hologram, who helmed last year's Roy Orbison hologram arena tour.
