Efterklang: wardrobe sponsored by prophylactics.
Hey, everyone—it’s Danish pop night, and the Raveonettes aren’t even playing! Efterklang sound like the Polyphonic Spree covering Björk’s soundtrack for Dancer in the Dark; their avant-pop constructions are sweeping and meticulous at the same time. Slaraffenland are moodier and a little more down home. — MIKAEL WOOD. 7 p.m., $12.
