OSHKOSH – Two of the biggest music festivals in Wisconsin — the 25-year-old Country USA and the 9-year-old Rock USA — are shutting down for good following COVID-related cancellations this year.

Together drawing about 200,000 people to Oshkosh’s Ford Festival Park each summer, the events featured such A-list headliners as Blake Shelton, Keith Urban and Ozzy Osbourne in recent years.

Their Neenah-based promoter, Hypervibe Inc., announced Monday it will file for Chapter 7 bankruptcy in the coming weeks so ticket holders for the scrapped 2020 events can try to get their money back.

Attorneys will send a letter or email with a bankruptcy claim to all ticket holders with instructions on how to fill it out and where to send it, according to Hypervibe. The bankruptcy filing will happen within several weeks.

“We are hopeful that the Bankruptcy trustee, who will be appointed upon the filing, will act quickly to liquidate assets and pay claims,” Hypervibe leaders said in a statement. “We have taken pains to individually list the ticketholders.”
