Erstwhile child actor and burgeoning rap superstar Aubrey “Drake” Graham did something brave on his debut album: He made it deeply personal and chillingly quiet. On the follow-up, with its ice-cave keyboards, glass-eyed R&B choruses, gaudy guests, and indispensable production from Noah “40? Shebib, he challenges his heroes to see how slow they can go. Meanwhile, Drake pines for a college ex, tempts a nubile nation, and tries to play big-boy rapper. But he’s never more interesting than when he’s calm, sad, and uncool.
