“foam angel” sounds like crackling radio transmissions from the ether; bright, chiming vocals spurt out incomplete phrases, creating an idyllic ambience. As the closing track on Ulla’s new album foam, it serves as a capstone for the record’s anxious feelings, communicated through fractured electronics and jittery loops. At the beginning, “foam angel” sounds like something out of the Ico soundtrack; bubbling synths coalesce into a delicate mist, followed by jazzy piano melodies that sputter in and out of focus alongside droning horns. There’s no climax, and the vocals don’t linger to completion, but this half-finished quality feels like Ulla’s working through turbulence with you. Ambient music often channels readymade bliss; “foam angel” wants to acknowledge uncertainty, and provide comfort therein.
