Listening to Rozi Plain is like searching for shapes in the clouds. In her mirage-like lyrics and mix of gently warped folk and nomadic jazz, you can stumble on moments of sharp recognition. A former art student, Plain is a longtime member of Kate Stables’ luminous folk band This Is the Kit and a fixture of the Cleaner Records collective, which she founded with fellow folk artist Rachael Dadd. All the while, she has nurtured her own ambitions. Prize, her fifth record, is a document of her evolution over the past 15 years, and, with its sprawling supporting cast, a tribute to the collective spirit that has defined her career.
