Singing for Justice reveals the story of Faith Petric (1915-2013), a political radical, musician, mother, worker and grandmother who united folk music and activism through almost a century of American social movements. She aided migrant workers in California during the Great Depression, built Liberty Ships during World War II, faced Cold War-era FBI surveillance, and marched for racial justice in Selma, AL. Over her long and purposeful life, Faith inspired all to take responsibility for social change, women and elders to defy stereotypes, and everyone she met to sing along.
