After more than two decades and eight studio albums together, Amy Ray and Emily Saliers, known to their legion of fans as Indigo Girls, have played thousands of shows. It's an audience that most artists would envy, one that eagerly awaits new music from the duo and greets older songs like old friends. Regardless of which way the pop culture breezes are blowing, who is topping the pop charts, who is dominating fashion magazine covers, or who is getting played on the radio, an Indigo Girls concert experience remains a constant. Whether it is staged at a campus coffeehouse or a sold-out Madison Square Garden, each Indigo Girls' show conveys their passion for fresh musical ideas, their respect for their audience and each other, their commitment to peace and social justice, and especially their unflagging enthusiasm for live performance. Amy and Emily have bravely and faithfully committed their voices, time, and money to the issues that concern them most – among them women's rights, protection of the environment, the rights of indigenous peoples, gay and lesbian rights, and gun control, creating a presence and impact outside conventional boundaries of the music world. "The most natural thing in the world for us is to marry social activism with our music because our music is so deeply rooted in life issues," says Emily. In 2015, the band released One Lost Day. The Indigo Girls continue to perform all over the world.
