Andy Warhol sets up his camera in early 1966 and lets it run while the Velvet Underground improvises in his Factory studio, working through feedback and drone with no set list and no cuts. The footage is raw by design: long unbroken takes, musicians noodling and adjusting amps, Warhol himself visible tinkering with lighting and camera position as part of the piece. There is no narration and no interview, just the band finding a sound in real time, which is the point of the exercise. The improvisation ends abruptly near the finish when police arrive, responding to noise complaints from neighbors, and the film catches the interruption as it happens rather than cutting away from it. As a document it captures the Velvet Underground at a formative moment, before their first album, working inside Warhol's method of pointing a camera at something and refusing to shape it into a conventional narrative. It stands as much as a Warhol film as a band recording.
