The Black Keys were one of the highlights of day one at the Isle of Wight festival, but they admitted they don't like going to them for fun.
"I've been to one festival," drummer Patrick Carney admitted. "Pitchfork festival in 2005 and I hated it, I gave it a 4.1.
"I didn't like standing around in a field in the sun for 10 hours," he said laughing.
Fortunately for fans, they don't mind playing them.
Their main stage slot at Isle of Wight was one of their first gigs back since Patrick dislocated his shoulder "like an idiot" according to him, back in January.
He was bodysurfing in St Barts in the Caribbean when he was hit by a wave.
"Dislocating your shoulder is not pleasant," he told us.
"It (the wave) wasn't even that big, the beach had eroded, this one section of the beach is dangerous apparently. I didn't know.
"I have never been manhandled by the ocean before but it is possible, it is actually ridiculously common to break your neck or shoulder from bodysurfing."
It meant cancelling a number of European tour dates while he recovered. "It is still not completely better yet," he explained.
"I have been going to physical therapy a lot. I can't sleep on it, I have to sleep on my right hand side, that is the most irritating thing."
The duo have a few more dates to finish up on this tour cycle and say then they will start thinking about album number nine.
And it has been a gradual process for them, only really seeing commercial success with their sixth album Brothers.
Some argue this can be the key to longevity rather than having huge success on your first record. The duo said that wasn't intentional.
"In this business, if you make it, it is a blessing and you've got to get in where you fit in," singer Dan Auerbach explained.
"If that means it takes us 13 years before we can headline a festival then so be it.
"But really the odds are so stacked against you to be the opener of a festival, let alone the headliner."
Patrick added jokingly: "It is actually more fun to not headline because you are then done working by 4pm."
Or maybe he was being serious.
