(Radio Iowa) – Iowa’s largest music festival is making some changes to address concerns raised by the extremely warm conditions this past summer. Hinterland Festival Director Sam Summers says one of those changes will include a refund process if temperatures are predicted to reach 90 degrees or higher. “I think that gives people, you know, the confidence that, like, you know, if we get to the point where it is very hot come August, and, you know, you make a decision you don’t want to go, you can return it,” he says.

The festival is held annually in Saint Charles, south of Des Moines, and Summers says they says are adding more space and shade this year at a new main stage location inside the festival grounds. “What that new space will do is allow people more space, more entrances, you know. We’ll have additional food areas,” he says.

Organizers also announced that Lana Del Rey, Tyler the Creator and Kacey Musgraves will headline the festival this year. It is scheduled from August 1st to August 3rd.
