“Lilith Fair: Building a Mystery” tells the untold story of the groundbreaking music festival featuring only women artists, started by iconic Canadian singer-songwriter Sarah McLachlan and her team in the late 1990s, in opposition to systematic industry barriers that limited women from playing together on a concert bill and getting back-to-back airplay on the radio. The documentary reunites and features interviews from original Lilith Fair artists Bonnie Raitt, Sheryl Crow, Erykah Badu, Paula Cole, Jewel, Mýa, Natalie Merchant, Indigo Girls, and Emmylou Harris and a new generation of artists who have carried the torch including Brandi Carlile and Olivia Rodrigo, among others. As the film celebrates the festival’s groundbreaking legacy and impact, it also confronts the backlash that tried to diminish it' and explores what Lilith means in today’s world.
