You’ve probably already met Swedish pop provocateur Tove Lo (pronounced “too-veh loo”). Her artistic thesis statement, “Habits (Stay High),” is a classic for a generation, and she secured some other hits in the middle of the last decade, as both an artist with “Talking Body” and a songwriter, working on Ellie Goulding’s “Love Me Like You Do.” After this initial commercial success, however, she turned left off the road to pop superstardom, producing darker and more intimate explorations of substance abuse and relationships in her “Lady Wood” album series, which earned Lo this writer’s admiration, though, understandably, less Top 40 airtime. She followed these nocturnal odysseys with 2019’s “Sunshine Kitty,” an album that attempted to soften her narratives’ edges, thereby sacrificing their essential grit. She has since left her major recording label to release music independently, and fortunately, her newest work “Dirt Femme” demonstrates the frankness and songwriting mastery that makes her a unique talent. It also illustrates Lo as an evolving artist, whose increasing ambition doesn’t always bloom here.
