Today marks the release of the second single from School of Seven Bells’ Alpinisms, “Iamundernodisguise.” An electronic calypso marked by ping-ponging percussion and one of the Deheza sisters’ slinkier melodies, “Iamundernodisguise” teases out School of Seven Bells’ sinister side within the parameters of a darkly catchy pop song. Repetition is the key here, as the Dehezas sing breathy, cryptic promises (“I am neither walker nor sleeper / I am neither sister, brother, son, nor daughter”) over and over as the beat goes on. The limited 7” vinyl + digital download is available now at The Ghostly Store, as are pre-orders for the extremely limited 180-gram vinyl release of Alpinisms. Get’em while they’re scalding.
