This extraordinary diary by Jonas Mekas chronicles Warhol's everyday life and work, and the social and cultural milieu that swirled around him. The film includes footage from the first public performance of the Velvet Underground at Delmonico's Hotel on January 13, 1966. Tracing an arc that veers from frenetic to reflective, the film opens with a segment taped at the Dom with Nico, and concludes with the Mass for Warhol at St. Patrick's Cathedral in 1990.
