No. 9: The Indigo Girls
Another Atlanta-based act, Amy Ray and Emily Saliers signed with Epic Records in 1989 and rode the late 80s folkie singer-songwriter wave kick-started by Tracy Chapman and Suzanne Vega into the 1990s. The Girls won a Grammy, helped put the Lilith Fair festival on the map and became spokeswomen for a number of causes, including LGBT rights & the abolishing of the death penalty.
