On their own, Johnny Balik’s sweet and tender vocals will stop you in your tracks. But when he pairs them with a slice of subdued and minimal soul, like on “I Need It,” the Toronto-raised singer is flat-out explosive. He might put a modern twist on it—making smirking a reference to Yeezy, for instance—but Balik has firmly planted himself in a vocal-pop tradition that’s nothing short of timeless.
