In his compelling new oscar-winning film Twenty Feet from Stardom, director Morgan Neville shines a spotlight on the untold true story of the backup singers behind some of the greatest musical legends of the 21st century. Triumphant and heart-breaking in equal measure, the film is both a tribute to the unsung talents who brought shape and style to popular music and a reflection on the conflicts, sacrifices and rewards of a career spent harmonising with others.
