Donald Glover has declared Bando Stone and the New World the last Childish Gambino album. The ostensible soundtrack to a feature-length movie of the same name, the hour-long project includes snippets of dialogue that hint at the film’s apocalyptic subject matter. The fact that the soundtrack is preceding the actual film is part of Glover’s strategy: He wants listeners to work to figure out what they’re listening to. “The soundtrack forces the audience to participate in a way that I don’t feel like most things force you to participate,” he says. These 17 tracks make for a satisfying swan song that synthesizes what came before with fresher ideas gleaned from the threshold of finality.
