Olivia Tremor Control have returned from a long hiatus to prove, again, that they’re the most interesting act from Athens, Georgia’s fabled Elephant 6 collective. What makes OTC so enticing? They wield both a keen sense of melodic loveliness within psych-pop parameters and a knack for darkly whimsical abstractions that wriggle down some mighty strange, imaginary-soundtrackish wormholes. Expect many wondrous cuts from their two classic ’90s LPs, Dusk At Cubist Castle and Black Foliage, and more.
