Last year, the members of Those Darlins stripped naked, huddled together, and snapped a photo for the cover of their album Blur the Line. They’ll bare it all again onstage at Rock & Roll Hotel tonight—emotionally, anyway. With the grit of four musical linebackers, the band leaves everything on the field during sets that explore their own psyches and feelings toward love, loss, and sex. The band’s current lineup features two men and two women, and for lead singer Nikki Darling, that kind of yin-and-yang is crucial to their garage-rock sound. “This may be the most important theme,” she says in a promotional interview. “Balance and finding balance within ourselves and others.” The group may juggle their complex feelings on stage, but leave your own emotional breakdowns at the door.Those Darlins perform with Diarrhea Planet and Paperhaus at 8 p.m. at Rock & Roll Hotel, 1353 H St. NE. $15.
