Music has always crossed borders before politics could. Long before genres had names, Black and Indigenous musicians were sharing songs, instruments, ceremonies, churches, dance halls, and stages. Their collaboration helped shape gospel, jazz, blues, folk, country, rock, powwow music, and hip-hop. Yet history often tells these stories separately—if it tells them at all. Black Turtle Island follows musicians, historians, cultural knowledge keepers, and descendants as they uncover an overlooked musical lineage stretching from the Underground Railroad to Harlem, Oklahoma, the Prairies, reservations, and today’s music scene. The film becomes both a celebration and a reclamation: revealing that Black and Indigenous musical histories have never been separate, they have always been intertwined.
