Like so much of her best work—the clever, tragic turns of phrase in “Space Cowboy,” the double portrait of a proud outcast and her tight-knit community on 2013’s Same Trailer Different Park—Musgraves’ latest album offers something of a bait and switch. In country music, breakups are discussed with the severity of mass extinction events: When life goes on after love, it is haunted, tortured, joyless. And when it doesn’t, dirty laundry is aired in public, bodies torched and disappeared. Musgraves, who filed for divorce in the summer of 2020, is aware of the gravity of her subject matter: “I wasn’t going to be a real country artist without at least one divorce under my belt,” she joked, and star-crossed arrives to both the highest expectations of her career and a storied lineage in the genre.
