Influential folk-rock duo

The Indigo Girls have steadfastly forged their own path through the music world for over two decades, and they don't show signs of slowing down any time soon. The duo of Amy Ray and Emily Saliers have now released 16 albums of breezy and lyrically adroit folk-rock, first emerging in the late 1980s alongside fellow Georgians R.E.M. (who played on the girl's eponymous major label debut). Throughout their career, they've explored issues of faith, love and politics, the jangly production and close-knit harmonies of their music sometimes belying the intelligence and seriousness of their lyrics.

With 15 million record sales under the belt, don't miss the influential folk-rock duo when they play a series of live dates this year.
