The European experimental band Vanishing Twin makes pop music for Dadaists. It’s all hard angles, unexpected turns and shifts. The band sings in multiple languages, creating an aura that feels rooted in the past. Its debut album, The Age of Immunology, dabbles in lounge pop, tropicália, and psych rock. Vanishing Twin takes the stage at Baby’s All Right, a venue in Williamsburg. —Sophie Kemp
