Slumber Party

While its name might conjure up images of toenail-painting and pillow-pummeling, the Detroit quartet Slumber Party sounds as if it would be the first band to doze off at an all-night girl-group get-together. Aliccia Berg’s wispy voice wafts over ghostly, distant guitars, her melodies bringing to mind a tranquilized version of ’60s girl groups or, at times, Nico’s stint as occasional lead singer of the Velvet Underground. Reverberating riffs often swarm over the low-key rhythm section, but near the end of the album the piano moves to the forefront, and guitars make only scattered outbursts. Hazy and trance-inducing, Slumber Party’s 13 potent sleeping pills should all inspire pleasant, if slightly psychedelic, dreams.
