Since 1985, Amy Ray and Emily Saliers have been making records as the Indigo Girls, the popular, politically active indie folk duo from Decatur, Georgia, that has had such hits as “Closer to Fine,” “Shed Your Skin,” and “Peace Tonight.” But for much of that time, Ray has been carving out quite a side career, having founded Daemon Records in 1990 and releasing a string of solo records over the last decade. Her latest, Lung of Love (Daemon, February 2012), is a lively collection of well-crafted songs that aren’t afraid to rock out. The follow-up to such discs as Stag (2001), Prom (2004), and Didn’t It Feel Kinder (2008), Lung of Love opens with the country-tinged “When You’re Gone, You’re Gone,” in which Ray sings, “I stood up at your wedding / I couldn’t hold my peace / I had a feeling you wanted me to / But you couldn’t let me see.” Ray then kicks into higher gear with “Glow,” an infectious blast of indie pop. “It felt good to be bad / It’s the best day I ever had,” she declares. The record also includes such tracks as the bluegrass “The Rock Is My Foundation,” the rave-up “Give It a Go,” and the harder-edged “From Haiti.” Ray and her band — Kaia Wilson on guitar, Melissa York on drums, Julie Wolf on keyboards, and Benjamin Williams on bass — will be at the Bell House on April 14 with Wilson opening up and at City Winery on April 15 at a special WFUV live broadcast for WFUV Marquee & City Winery VinoFile Members only.
