Foo Fighters play first Welsh gig in 17 years
Foo Fighters fans attending the band's Cardiff gig on Tuesday were advised to keep hydrated as the UK basks in warmth.
The Principality Stadium's roof was open for the band's first performance in the Welsh capital for 17 years.
Free water dispensers were available inside the arena as temperatures rose on the hottest day of the year so far in Wales.
Their Everything or Nothing at All tour is the band's first in the UK since the death of drummer Taylor Hawkins.
The 19-date, four-month tour coincides with the release of their 11th album But Here We Are, their sixth number one record.
They have already packed out stadiums in London, Manchester and Glasgow and, after playing in Cardiff, will head to Birmingham for the final date of the two-week UK stopover.
The Principality Stadium show follows sell-out concerts at the 70,000-capacity venue from fellow US superstars Taylor Swift, Bruce Springsteen and Pink.
The stadium advised fans to "stay safe and hydrated whilst queuing in potential hot weather".
"Once inside the stadium there are free water dispensers throughout the public concourses which we encourage fans to utilise," a spokesperson said.
"Extra water will be handed out from the barriers for those on the standing floor areas."
Bottles were not allowed in in the lower tier or standing areas of the venue.
"Collapsible bottles" were allowed in the middle and upper tiers but must be empty with tops removed upon arrival.
There were free water dispensers throughout the public concourses of the stadium.
In addition, extra water was handed out from the barriers for those on the standing floor areas.
