Brooklyn duo Teengirl Fantasy is only a few weeks from releasing its Tracer LP via True Panther/R&S, and follows up the first two leaks from that record today with new single “EFX.” The tune features a soulful vocal contribution from Los Angeles singer Kelela, who helps turn the outfit’s usual dreamy house productions into a kind of loose, swirling R&B. Get your fill of Teengirl Fantasy’s jam in the player below, and look for Tracer to drop on August 21.
