The Velvet Underground and Nico: A Symphony of Sound (1966) is an Andy Warhol film made at The Factory. It is 67 minutes long and was filmed in 16mm black and white. The film depicts a rehearsal of The Velvet Underground and Nico, and is essentially one long loose improvisation. Near the end of the film, the rehearsal is disrupted by the arrival of the New York police, supposedly in response to a noise complaint. The film was intended to be shown at live Velvet Underground shows during setup and tuning.
