Released as singles, the defiant tropical house of “Hotter Than Hell” and “Lost In Your Light”’s love-giddy electro-pop have already established Dua Lipa as a pop powerhouse distinguished by her husky, soulful voice. Now, on a debut album inspired by past relationships, she gets to showcase her striking range. From the stinging dismissal of a remorseful ex (“IDGAF”) to a tender duet with Chris Martin (“Homesick”), the Londoner’s richly emotive singing and songwriting maintain her steeply upward trajectory.
