OMAHA, Neb. (AP) – The main investor in a Council Bluffs music festival is suing the event’s organizers, and at least three vendors are seeking repayment of deposits and lost revenue. The Omaha World-Herald says the investor, Eric F. Marsh, is suing the Dom Group for more than $400,000. The group’s partners, Jason Dick and Darik Opperman, blame the problems at the three-day Grassroots Music Festival on Marsh.

The festival was plagued by absent performers, long lines, and vendors angry that they were barred at the last minute from doing business at the event. Marsh sued The Dom Group in part to ensure that he would be the festival’s exclusive vendor. In response, The Dom Group broke their contracts with previously signed vendors, most of which paid deposits of about $3,000 each.
