The only one that I've ever heard of is Sioux Falls SD if only because it's a city in South Dakota. They don't have many cities and even then it's population density is eclipsed by even your average Idaho city.

Bellville is an hour west of Houston in a town of 5000. Houston has several very large venues that could host festivals. Either it was so poorly planned that they didn't get any of them on time, the attendance is expected to be so low that the venues wouldn't deal with them, or they're trying to stay out of the mainstream spotlight because they're embarrassed about something.

It's still close enough that people from Houston, especially on the west side, could easily go, but there's got to be a reason they went an hour west instead of up in The Woodlands at Cynthia Woods or right in the middle of everything at Toyota or even a smaller place like White Oak Music Hall.

Ocalas grown a good bit lately. It was blowing up locally pre-covid and was one of the cities that saw a lot of transplants when people started flooding the state in the last few years. The city proper only has ~75k people in it but Marion county has ~400k and a large chunk of that remaining population is likely within 30 minutes of the city
