There are two ways to listen to Danish singer-songwriter MØ. You can sit and contemplate her serious lyrics or just give in and move to her entrancing electro-pop songs. MØ, the performance alias of Karen Marie Ørsted, has been recording singles on her own since 2012 and finally released her first studio album, Mythologies to Follow, this March. Though some tracks get bogged down by heavy synthesizers, her voice remains doubly potent, in part because she sings the melody, then lays her own harmony on top of it. “Pilgrim,” a dramatic, high-pitched rumination on journeys and freedom, is one of the album’s best blends of thought-provoking lyrics and vocal exercises. But the 26-year-old artist still infuses her live sets with bursts of youthful fun: Her version of the Spice Girls’ “Say You’ll Be There” has an ache at its core rather than sugary sweetness, but it’s danceable as ever. MØ performs with Holychild at 7 p.m. at 9:30 Club, 815 V St. NW. (202) 265-0930. 930.com.
