Singular adventures in pop oddness, recorded in a nuclear bunker in Norwich. Rosa Walton and Jenny Hollingworth’s debut has many childlike charms: over-sweetened teenage-witch vocals; liberal use of glockenspiel and recorder; and a low-boredom-threshold flightiness that carries the pair from dimly-lit trip-hop (“Deep Six Textbook”) to sinister folk (“Chocolate Sludge Cake”) and lo-fi rave and hip-hop (“Eat Shiitake Mushrooms”). There’s nothing infantile about their execution though, and they layer sound and ideas into enrapturing melodies with skill and fearlessness.
