Arvo Pärt is the most performed living composer in the world, but he doesn’t want to talk about his work—he tells his story in the music he creates. Pärt is known for his minimalistic style based on his own strict compositional technique, which employs sensitivity, humor, and energy to evoke a feeling of wholeness and beauty. His intense collaboration with the Cello Octet Amsterdam is at the heart of this documentary, along with other performers and artists—and audiences—who are attracted to the spiritual power of his approach.
