This was a side show during the Beck/Phoenix Summer Odyssey tour, in which, on a night off, Beck dropped into Utah and played a solo acoustic gig.
La Lom opened.
Setlist from setlist.com, unverified, but seems pretty accurate to what he usually does for solo gigs. It's possible, he brought some of his band with him though. I would not be surprised if La Lom performed with him on the last handful of songs, as well, as they did at a show in LA a few months prior.
