Coachella 2018 begins this weekend, but it looks like it's not all fun and games this year. Oregon music festival Soul'd Out is suing Coachella, arguing that the festival's radius clause violates anti-trust and unfair competition laws and creates "an illegal monopoly in the market for live music festival performances," Billboard reports.

An alleged copy of the radius clause states that artists playing Coachella are restricted from playing "any festival or themed event" in California, Nevada, Oregon, Washington or Arizona from December 15, 2017, until May 7, 2018. Nicholas F. Aldrich, lawyer for Soul'd Out founders Nicholas Harris and Haytham Abdulhadi, argues that Goldenvoice and AEG are violating anti-trust statues by "unreasonably restricting price and cost of competition among live concert venues" and "limiting entry or expansion of competitors" in "the states of California, Nevada, Oregon, Washington, or Arizona." Aldrich says that several artists, including SZA and Daniel Caesar, declined to play Soul'd Out, citing "the unlawful radius clause in their contracts with Coachella as the sole reason that they cannot do so."

Soul'd Out happens this year April 18-22 with Erykah Badu, De La Soul, Wyclef Jean, BJ the Chicago Kid, Noname, Bettye LaVette, J.I.D., SZA's TDE labelmate SiR, and more.
