L.A.'s Peaking Lights are Indra Dunis and Aaron Coyes, a husband-wife duo who meld psychedelia into bubbly dub ditties. On their fourth album, the pair explore the more lysergic parts of our world through gossamer electronica, buoyant vocal effects and metaphysical grooves. Recent years of parenting have expanded their sense of awe, emerging in wide-eyed, twinkly numbers like "Little Light." While their simplistic lyrics can leave listeners yearning for further enlightenment, sometimes the earnestness works, as on the lullaby-esque "Tell Me Your Song." It's not all bad when we don't understand what's beyond us, Cosmic Logic seems to suggest. Just being moved can be enough.
