Dangerous Woman is an outing that showcases Ariana Grande’s increasingly ferocious voice and a newfound edge—in fact, it’s a swaggering step forward. She joins forces with Nicki Minaj for the devilish reggae of “Side to Side,” seduces Lil Wayne on the breathy “Let Me Love You,” and, expertly harnessing those extraordinary vocals, turns slinky Max Martin cut “Into You” into one of 2016’s most glorious pop moments.
