Amy Ray, known for her rocking solo shows and as half of the beloved Atlanta folk duo Indigo Girls, will headline the Sunday stage at Atlanta Pride, organizers announced today.

The annual festival is set for Oct. 13-14 in Piedmont Park. Pride officials had already announced that Andy Bell of Erasure would headline Saturday's entertainment.

Ray's performance is set for Sunday evening, immediately before the Starlight Cabaret drag extravaganza closes out the festival.

“We are thrilled to announce Amy Ray as our Sunday headliner!” said Glen Paul Freedman, Atlanta Pride board chair, in a press release announcing the show. “The 2012 line-up is shaping up to be a great one and with the addition of Amy Ray, our festival goers are sure to be entertained.”

The full festival entertainment lineup will be announced in September.

Ray has already played Atlanta Pride several times as part of Indigo Girls, including headlining shows in 1996 and 2005.

"Fans familiar with her only as part of the Indigo Girls will be surprised to learn that Ray’s solo act is loud and raucous by comparison," the Pride press release noted. "Her sultry voice and stomping guitar licks are sure to entertain new, old, duo and solo fans alike."

 In 2010, Ray and Indigo Girls partner Emily Saliers sat down with GA Voice to record a video wishing Atlanta Pride a happy 40th anniversary.
