Hill contributed her voice to the soundtrack for "What Happened, Miss Simone?", a 2015 documentary about the life of Nina Simone, an American singer, pianist, and civil rights activist. Hill was originally supposed to record only two songs for the record, but ended up recording six. She also served as a producer on the compilation alongside Robert Glasper. Hill said of her connection to Simone: "Because I fed on this music ... I believed I always had a right to have a voice. Her example is clearly a form of sustenance to a generation needing to find theirs. What a gift." NPR critically praised Hill's performance on the soundtrack, stating: "This album mainly showcases Lauryn Hill's breadth and dexterity. Not formally marketed as Hill's comeback album, her six tracks here make this her most comprehensive set of studio recordings since "The Miseducation of Lauryn Hill" in 1998."
