For years, the artist Meryl McMaster has been tapping into her mixed ancestry to make epic large-scale photographs. Now, a new exhibition of her work, “Meryl McMaster: Bloodline,” is traveling the country. The exhibition takes you from some of Meryl’s early work when she was still in school, to a new body of work that’s based on a recent discovery — a diary and letter written by her great-grandmother, living in Red Pheasant Cree Nation in Saskatchewan. Meryl tells guest host Talia Schlanger what it feels like to have a retrospective of her career in her 30s, what taking self-portraits has taught her about herself, and how she’s telling her family's story through her work.
