If Lena Dunham is the voice of the millennial generation, she should take some cues from Waxahatchee, the solo project of Katie Crutchfield. On her stark, beautiful debut, American Weekend, Crutchfield sings hauntingly bare folk tunes about the loneliness and frustration characteristic of the average quarterlife crisis. As she moans on “Grass Stains”: “I don’t care if I’m too young to be unhappy”—a sobering line that encapsulates the beguiling uncertainty of young adulthood more authentically than any line of Dunham’s dialogue. That’s because Crutchfield isn’t anything like the Girls girls. She’s been touring and playing music in the DIY punk scene for the better part of a decade and wears her punk-rock ethos like a badge of honor. With her latest record, Cerulean Salt, she leaves behind the stripped down, DIY home recordings in favor of a more polished sound. Though the production may have grown up a bit, the lyrics are still dripping with the same youthful anxiety, sans the bourgeois Bushwick vibe.

Waxahatchee performs with Passing Phases and Sick Sick Birds at 7 p.m. at Casa Fiesta, 4910 Wisconsin Ave. NW. Free. (202) 244-8888. casafiesta.com.
