In his first feature-length documentary, Sterlin Harjo explores early American songs in what’s now the United States. The film, titled “This May be the Last Time,” premiered at the Sundance Film Festival and will be available on VOD and DVD. November 11.

Harjo’s grandfather disappeared in Oklahoma in 1962, and Harjo set out to find out what happened to him. Seminoles supported him in his search along the way, singing songs that turned out to be from Scottish missionaries, enslaved black people and Natives. The resulting documentary casts new light on what we think about early American music.
