Paradiso Festival, one of the most popular annual EDM events in Washington state, may be in trouble after one of its owning companies is suing the other.

Insomniac Events, a California-based event production company that co-promotes the festival, filed a lawsuit Jan. 28 against Seattle-based USC Events. Insomniac Events alleges in the lawsuit that USC mismanaged $1.2 million. The company says it gave USC $2 million in advance to pay for artist and vendor fees, which vendors and artists claim they didn’t receive.

Attorneys from Insomniac Events did not respond to request for comment, and USC had similarly not responded at the time of publication.

The lawsuit asks the judge to dissolve a co-promotion agreement between the two companies that had allowed them to put on the festival since 2013. Further, the lawsuit asked for a permanent injunction against USC, barring the company from promoting and booking future Paradiso Festivals. The two-day event usually occurs in mid-June and attracts about 25,000 people each day.

Lastly, the lawsuit asked for financial compensation, with the amount to be decided at trial.
