What would a pop song be without the riffs, refrains, and harmonies of its backup vocalists? Although these singers are usually relegated to the margins, and few, if any, become household names, their work has defined countless songs that remain in our hearts and collective consciousness. Twenty Feet from Stardom juxtaposes interviews with industry legends (Bruce Springsteen, Bette Midler and others) and the relative unknowns who support them like Darlene Love, Merry Clayton, Lisa Fischer and Judith Hill as they illuminate the art of melding their own distinct voices with lead vocals and reveal their desires for careers as solo artists.
