Tens of thousands of music lovers are descending upon Glasgow Green for the first day of Scotland’s largest music festival.
TRNSMT has returned to its summer slot after two years of Covid disruption.
The Bootleg Beatles got the festival underway on the main stage, which is being headlined by Scottish singer-songwriter Paolo Nutini on Friday.
There will also be headline sets from The Strokes and Lewis Capaldi on Saturday and Sunday.
The festival did not take place in 2020 because of the pandemic and was delayed until mid-September last year.
About 50,000 people are expected to attend the event at Glasgow Green on each of the three days.
Organizers have advised those attending not to travel by car as there is no parking available and surrounding roads will be closed.
They also warned that rail travel could be hit by last-minute cancellations and extremely limited rail services across Scotland.
This is due to a temporary timetable currently in place after a pay dispute which could mean some struggle to get a train when the festival ends.
On Sunday night, when Scots singer-songwriter Lewis Capaldi is set to close the festival at 23:00, there will be no trains when fans leave.
The first TRNSMT festival took place over three days in July 2017. It was widely seen as a replacement for T in The Park, which was run by the same promoters and operated in the same July timeslot for 23 years until 2016.
In 2020, TRNSMT was postponed because of Covid, and in July last year, it was delayed again because of concerns over the spread of the virus.
It eventually took place from 10 to 12 September 2021.
This year’s line-up includes Sam Fender, Nile Rodgers and Chic, Foals, Fontaines DC, Wet Leg, and Wolf Alice.
Paisley-born Paolo Nutini, who recently returned from an eight-year hiatus with a new album, is the headline act on a Friday night.
New York rock band The Strokes are Saturday’s headline act, with Lewis Capaldi closing the festival on Sunday night.
