In from the Fading Frontier, Bradford Cox and his Atlanta band of indie-rockers and psych-poppers shake off the desert dust of Coachella and plug in at Observatory North Park Friday night.

Dryw Keltz has a chat with the band’s big-bearded frontman, Stephen McBean, in advance of Tuesday night’s show at Casbah.
