Great artists often find beauty in things pop culture has long discarded, but Ecstatic Sunshine has found inspiration in an ignored corner of indie-rock­: late ’90s Midwestern emo. Just as Warhol resurrected Elvis iconography by ditching the fat years, this Baltimore-based duo has realized that if bands like Joan of Arc were stripped of their strained vocals and their pretentious lyrics, the remainder would be pleasant yet vaguely psychedelic guitar instrumentals. By adapting those basic ideas and adding a little bit of additional art-school grit, Ecstatic Sunshine has stumbled upon a heap of sublime and kinetic melodies that reclaim the guitar from those who might wrongly use it for macho posturing, drone noise, or anything that might be featured on an iPod commercial. Ecstatic Sunshine performs with Dirty Projectors at 9 p.m. Wednesday, Sept. 26, at the Black Cat, 1811 14th St. NW. $10. (202) 667-7960.
