XVRHLDY and Trapo have never been romantic, but you’re tempted to think otherwise on “Polaroids,” an impossibly smooth rework of Chris McClenney and Iamnobodi‘s “Natural.” Trapo, a 16-year-old triple threat from Wisconsin, sweet talks between a dizzying double time, while X and his girl scramble from photo shoots to skinny dips in the Atlantic. Trapo’s freneticism and XVRHLDY’s weighty delivery create a remarkable balance, and the duo plans to release a project that will exude the same smooth vibe as “Polaroids.”
