Short, sweet, and wildly kinetic, SOPHIE's debut album goes off like a chain reaction in a bouncy-ball factory. Stripping pop melodies and club rhythms down to their essence, the UK producer delights in detuned trance stabs and hiccupping freestyle on "Bipp," and on "Lemonade" she unleashes teakettle squeal and hypnotic bubblegum pop. She can go dark: "L.O.V.E." buzzes with ominous drones, and "Msmsmsm" is a maelstrom of metallic trap drums. But on "Hard," "Vyzee," and "Just Like We Never Said Goodbye," playful rhythms and spine-tingling synths keep the mood positively giddy.
