This is the show at which Beck was "discovered" by Rob Schnapf and Margaret Mittleman. While other acts at this event were definitely recorded, Beck's set doesn't seem to have been. This is probably because he was just sort of playing on the street and wasn't one of the official acts.
A later article about Mittleman included her description:
"It was in 1992 that a momentous event occurred, when Mittleman first saw Beck (Hansen) perform. "I saw Beck performing solo at the ‘Sunset Junction’ street fair in Silver Lake," said Mittleman. "I was with my boyfriend (and now husband) Rob Schnapf, who was a partner in Bong Load Records during this time. We were walking around, and we saw Beck playing acoustic guitar and singing under this little tent, right on the street. I just got drawn in; he had an unique sound and look, and his lyrics were hilarious. After his show, I talked to him for awhile, and gave him my card."
It was three months later when Mittleman next met with Beck. Beck called her, they had a lengthy phone conversation, and she invited Beck up to the BMG office. Beck brought a cassette of 10 songs he had recently recorded, and played the demos for Mittleman.
"The demos were rough, but they definitely showed potential," said Mittleman. "I wanted to immediately offer Beck a publishing deal, but BMG decided to hold off a bit. It was when Beck later played us ‘Loser’ and some excellent new songs, that BMG signed Beck to the publishing deal."
