Nandi Rose, the ethereal voice behind Half Waif, announced her new album Mythopoetics last month. A batch of songs are already out, and this newest single, “Sodium & Cigarettes,” keeps up the momentum. It's a breathtaking ballad that lingers in different states of consciousness: “In my dreams, we were flying/ Now we’re falling back.” It's as transcendental as Weyes Blood or Sun June; it's meant to be listened to alone in a vulnerable moment.
