According to Brooklyn Vegan, a vintage recording of the Velvet Underground playing at Dallas Peace Day, a Vietnam War protest that happened on October 15, 1969, has been released. The footage is part of a collection of hundreds of videos, most of them unmarked and unidentified, in the holdings of the G. William Jones Film & Video Collection at the SMU Library archives.

The band were in Dallas for a week of performances and were one of many artists, including Lou Rawls, to play the Peace Day protest. G. William Jones Film & Video Collection uploaded a few long clips from the protest, which includes the band performing “I’m Waiting for the Man,” “Beginning to See the Light” and “I’m Set Free,” and there’s an interview with Sterling Morrison as well. The sound is muffled but it is captivating nonetheless.

Velvet Underground found their audience when artist Andy Warhol spotted them and set them up at his Manhattan studio. They became labeled as groundbreaking musicians as they reversed the stereotypical rock band as they took the world. The staying power of the band’s effect on the music industry stems from their songs and style, which has been emulated by rockers ever since their debut.
