OLIVIA RODRIGO-SOUR

On “Sour,” which deploys sweet pop and tart punk equally well, Rodrigo’s real study is of the unsteady self, the way in which people — young people, especially, but by no means exclusively — contort themselves into the shapes laid out before them. It is about the wages of being clay, not the mold. But Rodrigo herself is balancing several lives at once now — new celebrity, new pop superstar, holdover child actress, and more. And “Sour” is the first step toward insisting that the gaze that matters most is the one in the mirror, no matter who else is looking.
