A sensation at the 2013 Sundance Film Festival, this irresistibly entertaining documentary shines a spotlight on the gifted backup singers behind some of the greatest musical legends of our time. Triumphant and poignant in equal measure, and spanning a wide range of styles and genres, the film is both a tribute to the unsung voices that shaped popular music and a reflection on their sacrifices and rewards living in the shadows. The gifted artists who share stories about their careers include Darlene Love, Merry Clayton, Lisa Fischer, Tata Vega and Judith Hill, and the film also includes intimate interviews with such superstars as Bruce Springsteen, Stevie Wonder, Mick Jagger and Sting, to name just a few. This time around, however, the big names take a backseat to the backup singers, whose lives, stories and music at last take center stage. Director: Morgan Neville. (US 2013) 90 min.
