Based on name alone, you might expect to find a band called Mothers at a family-friendly music festival like Gathering of the Vibes. But the Mothers that will headline DC9 this week delivers music more angsty than stuff you’d expect from the high-waisted-jean-wearing matriarchs we know and love. Beginning as a solo act, Mothers singer and guitarist Kristine Leschper still holds on to her quiet and haunting style. Like Angel Olsen’s, Leschper’s voice crawls over choppy guitars or softly rests on tinged, electronic piano. A sense of longing tugs at each chord, notably on tracks like “burden of proof (pt. 1).” Because the group’s sound continues to evolve, most of its recorded tracks are live, a quality that builds on its DIY aesthetic. Leschper’s spell-binding and simple arrangements allow her to cast a charm over an entire room. Mothers performs at 9 p.m. at DC9, 1940 9th St. NW. $10. (202) 483-5000. dcnine.com.
