Phantogram, a duo whose work is based in electronica dreamily sieved through trip-hop, shoe-gaze and psychedelica, make an appearance at Sunshine Theater (120 Central SW) on Friday, Dec. 4. Members Sarah Barthel and Josh Carter use elements of multiple, generally rocked-out genres to fashion a sound that is formidable for its attention to somnolent sexiness and the thickly churning undercurrent of urban experience expressed as incessantly compelling beats. After their 2010 break-out album Eyelid Movies, Phantogram has demonstrated mastery of their underlying influences—as well as their staying power in the increasingly overwrought EDM/chillwave milieu—by collaborating with the likes of Big Boi (OutKast) as well as Steven Drozd (Flaming Lips). Additionally, their latest recording, Voices, is indicative of an evolution that pushes the duo past mere derivation and into an universe populated by nuance and knowing reflections on life and experience, as heard in the tracks “Never Going Home” and “Bill Murray.” The latter features static-laced rhythms, languid guitar-work and plaintive vocalizations that travel well beyond genre but still reminiscent to Drozd’s groundbreaking arrangements on The Soft Bulletin. Tickets for Phantogram are $23 dollars, but it’s a 13+ show that is bound to be as unforgettable as it is boundless.
