High-pitched keyboard notes rain like shards of glass over a round, insistent house beat on Brooklyn producer Shams’ new single “Nest,” featuring Murphy Maxwell on backup vocals. It’s the first from his forthcoming debut album on NYC label Hoss Records and reads like a missive from the darkest corner of the dancefloor. Do you remember those first days out of the nest? sings Shams with what sounds like a manic grin on his face. Ideal listening for this Friday 13th evening, then.
