Ground Zero of Dosloc says in this article
that, in addition to opening for Beck, Dosloc played a show with Beck. I'm not sure when that would have been.
There was however a regular tour gig with That Dog and Link according the image below. Maybe Dosloc opened the second one?
I've seen a few comments about how crazy packed it was (not unusual for this section of the tour; Beck was playing venues way too small for his MTV fame at the time). One note said " Kansas City's Rhumba Box (a venue at 10th Street and McGee that lasted from summer 1993 to spring 1994) had its moments, particularly a Beck concert at the height of his "Loser" fame that had desperate teenage fans literally hanging from rafters for a view."
