This film follows composer and performer Max Richter as he consolidates an ambitious performance of his critically acclaimed eight-hour opus, Sleep. The film plunges deeply into the artist’s life and process, transcending the work to explore his legacy. Personal reflections from Max Richter, and visual archive from his long-term creative partner, the BAFTA winning filmmaker, Yulia Mahr - the co-architect of SLEEP – help build this intimate portrait – along with contributions that illuminate both the science and story behind the work.
