For decades, Barbara Dane lent her stellar singing voice to social-justice movements in the Bay Area and beyond, garnering an impressive FBI file along the way. Deeply respected by fellow luminaries in folk, blues and jazz, Dane built a far-reaching legacy with music, activism, and love. As Maureen Gosling’s celebratory portrait reveals, early solidarity with those suffering racial and economic injustice sparked Dane’s passion to use her talent to sustain marginalized people. Rather than chase stardom, she followed her own maternal instincts to root herself and her family among generations of activist performers. Bonnie Raitt, Jane Fonda and other notables attest to Dane’s unique way of shaping and being shaped by tumultuous social revolutions from the 1950s on. Nearing 90, Dane triumphantly tours with piano virtuoso Tammy Hall to celebrate a life of staying awake and connected, true to her ideals. One star among many illuminates so much.

"I especially hope to inspire young women, because I often feel like so much emphasis is put on how beautiful you are, and how thin you are, and not a lot of emphasis is put on what you can do and how smart you are. I'd like to change the emphasis of what's important when looking at a woman." Filmed in San Francisco in 2000, Margaret Kilgallen (1967-2001) discusses the female figures she incorporated into many of her paintings and graffiti tags. Loosely based on women she discovered while listening to folk records, watching buck dance videos, or reading about the history of swimming, Kilgallen painted her heroines to inspire others and to change how society looks at women. Three of Kilgallen's heroines—Matokie Slaughter, Algia Mae Hinton, and Fanny Durack—are shown and heard through archival recordings. Kilgallen is shown tagging train cars with her husband, artist Barry McGee, in a Bay Area rail yard and painting in her studio at UC Berkeley (source: Art21).
