The members of Florida Georgia Line and their tour manager are being sued for $15 million by a concert promotion company in Utah.

The Salt Lake Tribune reports that Country Explosion LLC filed the suit in US District Court last week. The company staged the recent Country Explosion, which is billed as the largest country music festival in Utah. This year's event ran from July 17-20 and featured a lineup of some of the top acts in country music, with headliners including Rascal Flatts, Reba McEntire and Toby Keith. Florida Georgia Line headlined the festival's final evening.

According to the legal filing, Country Explosion LLC gave road manager Troy Johnson a check for $205,000 on July 20, but asked Johnson not to cash the check until three days later.

"It was also explained that the reason for the delay was that the check would be covered by box office receipts that would clear within the next 72 hours," attorney David Drake writes.

The suit alleges that Johnson agreed to wait three days, but then cashed the check the following day, thereby breaching the oral agreement between the two parties.

"As if adding insult to injury, on July 22, 2014, Johnson announced by email to the William Morris Agency Nashville and to other artists and booking agencies in Nashville, that the check had bounced, making Country [Explosion] absolutely toxic among the artists and booking agencies in Nashville," the brief continues. "This has also had repercussions in the entertainment industry around the whole country."

Country Explosion claims Johnson and Florida Georgia Line "intentionally misrepresented" that the check had bounced, knowing they are already trying to book acts for next year's festival. They say they have not been able to book any acts since the July 22 email. They are asking for at least $15 million in financial damages, and possibly more if the company ends up going out of business. They are also asking that the defendants notify everyone who received the initial email about the bounced check that their statements "were incorrect."

Florida Georgia Line shot to national fame with the overwhelming success of their debut single, 'Cruise,' which has shattered several longstanding chart records. Their debut album, 'Here's to the Good Times,' has been certified multi-platinum. Their current single, 'Dirt,' is the lead single from their highly-anticipated sophomore album, which is expected later this year.

The members of Florida Georgia Line have not commented publicly on the lawsuit.
