Soul Sisters was thrilled to join Amy Ray and Emily Saliers of the iconic power duo Indigo Girls before their sold-out show at New Jersey's Wellmont Theater, where swarms of fans had come from across the east coast to hear the harmonious voices that defined many a '90s adolescence (and continue to do so with new generations, their sixteenth studio album out just last year). From "Closer to Fine" to "Galileo," "Power of Two" to "Ghost," Indigo Girls possess a certain symbolic place in our cultural minds - for better or worse, as Ray and Saliers are very quick to address.
