Hinterland, a two-day music festival held annually in St. Charles, is canceling its planned 2020 event and will return in 2021 with the same lineup of planned musicians, the festival announced today. Hinterland is scheduled to take place Aug. 6-8 in 2021, with a full day of music planned for Friday instead of just evening sets as usual. All tickets already purchased will be valid for the 2021 dates; refunds may be requested at realperson@hinterlandiowa.com by July 17, 2020.
