I've seen some reports of Beck playing at the OK Hotel in 1992 as well. They probably meant this show, but I'm not sure.
Chris Ballew remembered this show. He had seen Beck the night before, liked it, came to this show. He recalled that, "[Beck's] DAT player that was playing the backing tracks for 'Loser' broke, so I hopped up onstage with a bunch of harmonicas and we had a harmonica duel and saved the show." This led directly to Ballew joining Beck's band when he went on tour the next month.
