Michael Angelakos can be counted on to deliver infectiously saccharine synth-pop as Passion Pit, which is both his solo project (he writes, records, and produces all the studio LPs by himself) and a band (on the road, the singer/keyboardist is joined by musicians on guitars, synths, bass, and drums). He self-released Passion Pit’s fourth and last album, Tremendous Sea of Love, which is just as joyously uplifting as we all expected, and as the title suggests, although the title track is surprisingly gauzy and abstracted. by Leilani Polk
