The Kings of Leon are to repeat a gig in Dallas after cutting short a show because their lead singer complained that it was too hot to perform.
Caleb Followill walked off stage on Friday, saying his voice was suffering because of the heat.
He left the rest of the band to announce the abrupt end of the show to a booing audience.
"I know you guys f**king hate us," said guitarist and brother Jared Followill. "It's really not our fault. We will be back as soon as possible. F**king hate Caleb, not us."
He then apologised on Twitter and hinted at deeper problems within the group.
"I know you guys aren't stupid," he wrote. "I can't lie. There are problems in our band bigger than not drinking enough Gatorade."
The Dallas show has been rescheduled for September 22.
