Before you hit “play,” go ahead and Dim the Lights—or draw the shades, if it’s still light out ‘round your way. It would be a shame to dampen the moody, majestic vibe of CREEP‘s Booth debut by listening to it in the wrong ambiance. This freshly-selected single sees crewmates Lauren Dillard and Lauren Flax mixing live strings with reverb-drenched synths and drums to create a mesmerizing backdrop for guest vocals from Sia, the Interscope signee who brought us Elastic Heart. Interest piqued? More lush, innovative jams await on the B.K. twosome’s Echoes LP, scheduled to drop November 12, via Dazed Digital.
