Severe weather forced Kings of Leon to cancel their headlining set at Firefly Festival in Dover, Delaware. Just minutes before the band was supposed to perform on the fest's main stage on Saturday night, June 20, it was announced over the PA system that "dangerous, inclement weather is coming." Fans were subsequently asked to "clear the festival site."

Kings of Leon's set was originally scheduled to begin at 10:30 P.M., but the organizers moved it up to 09:45 P.M. in a bid to avoid the bad weather. The lightning storm and heavy rain then prompted concertgoers to take down all pop-up tents and poles. They remained in their vehicles during the storm.

Following the cancellation, KoL's member apologized to fans via Twitter. "So sorry Firefly. Mother Nature apparently was not given VIP passes and decided to be a bastard. I was ready to melt multiple faces," drummer Nathan Followill said.

His bandmate and brother Jared Followill added, "We have the worst luck. Flew up to Delaware. Did press. Meet and greets. The only thing I was looking forward to was playing the show... Thanks to @LiveAtFirefly for being such a cool festival. So bummed we got rained out. Hopefully we can be back soon."

The storm didn't only affect KoL's performance. Kid Cudi's set was cut off after only 20 minutes. Appearing 10 minutes late, the rapper treated the crowd to "Revofev", "Down and Out" and "Soundtrack 2 My Life" before his "Mojo So Dope" got interrupted by a Firefly official who came onstage and told fans to leave the site.
