Buffy Sainte-Marie’s singing career began at a time when the country’s knowledge and awareness of Indigenous people was limited. Growing up as an adoptee, she admits limited knowledge of her own heritage. But by educating herself, connecting with like-minded people, and honing her talent, Sainte-Marie became a trailblazer and an artist whose gift remains current and laudable. Monday on Native America Calling in this encore presentation, Shawn Spruce talks with her about the early years of singing, the foundation it provided for her current work, and the PBS documentary that paints a portrait of her many talents.
