We believe this was the first show of Judy & the Loadies, sometime in 1990. It was at a bar called the Jambalaya on H Street, between 9th and 10th in Arcata, California. I think it's still there, but it's a restaurant now.
Judiths friend Catharine was in the band for this show, seen at the far left of the photo. The only clue Chris is there is from the kick drum in the lower right corner.
