—The Indigo Girls are set to perform the Fremont Theater June 30, in San Luis Obispo. Doors open at 8 p.m. and show starts at 9 p.m. For tickets, visit Boo Boo Records or purchase at www.eventbrite.com.

Decades into their career, the Indigo Girls still amaze conventional pundits with their ability to grow and thrive no matter what the state of the music industry is at any given point. The duo’s constant touring, as well as staunch dedication to a number of social and environmental causes, has earned them a fervidly devoted following over the years. So many artists who launched their careers in the late 1980s have slipped from our collective memory. In contrast, the Indigo Girls stand tall, having earned the lasting respect and devotion of a multi-generational audience which continues to experience their creative evolution in the studio and on stage. The adventure may take the form of an adrenaline-fueled live CD or a warm reflective holiday album or a collection of songs that can veer from the raucous to intimate in the blink of an eye. No matter where their creative journey takes them, they hold out a hand to their listeners and we get to feel it all.
