Many fans are excited to hear Cross Canadian Ragweed, who is playing for the first time since they got back together.

"I'm super excited cause there's not a lot of bands out there that are red dirt anymore, and so I love this kind of stuff, I think that's why the turnout is how it is," said one fan.
