In the aftermath of Creepoid’s final show, its offshoot, Lovelorn, has emerged with a debut single. “Chains” finds Anna Troxell, Patrick Troxell, and PeteJoe Urban pulling listeners into a haunted space. Anna’s vocals serve as the candle light leading the way through a labyrinth, as the backend marches in line and the guitar stirs, doubling down on the menacing atmospherics. You can catch Lovelorn’s first live Philly performance at Underground Arts on Sunday, March 25, with Dead Meadow and Dallas Acid.
