Another solicitation for the Rhode Island College show:

Someone provided a venue name for the 1990 Jacksonville, FL show: Kahootz
https://www.setlist.fm/setlist/nine-...-2b85eca2.html
I asked how he knew the venue name, but it's only been a couple hours, so he hasn't responded. Looking at his concert history, though, he seems to be a Florida native, so he may have attended the show. I did a little searching, but couldn't find anything on the Internet linking Nine Inch Nails to "Kahootz". Maybe you might have more success searching newspapers, now that you know the venue name.
I did find some corroborating information about "Kahootz" existing. There is a trademark registration for it
here. And the mark was owned by
Crown Leisure Corp. which I found owned at least a couple other nightclubs in FL in the late 80's/early 90's.
