Thousands of music fans have arrived on Glasgow Green for Scotland’s biggest music festival TRNSMT.
Around 50,000 people are expected to attend each day of the event, which will run from Friday to Sunday and is headlined by Liam Gallagher, Gerry Cinnamon and Calvin Harris.
Warm and sunny weather accompanied the opening day, with acts including Garbage, the Snuts, the Last Dinner Party, Sugababes and Example playing across three stages.
However some fans will have to chose between seeing the end of the headline performances and getting home, after rail operator ScotRail warned a reduced timetable meant the last train on some services will leave before each night concludes.
Fans arriving on Friday were in high spirits though, with the soulful sound of Jalen Ngonda opening proceedings on the Main Stage.
Irish pop-rock band Picture Perfect then sparked some early sing-a-longs from sweltering fans.
Hannah Brunatti was joined by her friends Kirsty Brown and Aqsa Riaz, with her main highlight coming on Saturday.
She said: “I’ve seen Gerry Cinnamon before, when he played Hampden, and I’m really excited to see him again.
Asqa added: “I saw Calvin Harris before in Ibiza, so it’ll be hard to top that – but I’m sure he’ll be amazing.”
Evan Young was one of the earliest arrivals after gates opened.
He said: “I’m looking forward to seeing Liam Gallagher – he’s doing Definitely Maybe in full.
“I’m here for all three days so I’m wanting to see some of the smaller bands too, like the Raytons and Bilk.”
And not all the fans were from Scotland.
The Davis family – parents Simon and Sarah and children Pippa and Scarlett – had travelled from near Bristol and were looking forward to seeing Liam Gallagher and Declan McKenna.
They said they couldn’t believe the good weather and were hoping it stayed the same all weekend.
McKenna himself was glad to be at the event.
He told BBC Scotland News: “I’m just trying to stay calm and relaxed – there’s massages backstage.
“There’s a really good energy in the crowd.”
In a social media post ScotRail said that people going to the festival should “consider their travel options home after the event has finished” due to the ongoing reduction in services.
Cammy Barnes, from Fife, who appeared on Britain’s Got Talent, is also performing.
He told BBC Radio Scotland’s Drivetime programme: “This is everything you dream as a musician. I’m totally buzzing. I’m excited.
“A post popped up on my Facebook today – 19 years ago today I bought my first guitar. That’s mad that that was today and now I’m playing the biggest festival.
“I didn’t ever think I’d get the opportunity to play TRNSMT. I didn’t think I was cool enough but here we are.”
He added: “I’ve been hustling for the last 10 years. Britain’s Got Talent was just an extra wee cherry on the cake. I’ve played every single venue across the country.”

The festival will continue until Sunday, with Scottish DJ Calvin Harris closing the event.
Weather is expected to remain cloudy throughout Saturday, with the possibility of rain arriving on Sunday.
Music fans who are not going can follow the festival through the BBC all weekend.
BBC One and BBC Scotland will present highlights every night while a number of full performances will also be available to watch on the iPlayer.
BBC Radio 1 and Radio Scotland will also be broadcasting live from the festival, with acts including Chase & Status, Courteeners, Natasha Bedingfield, CMAT and Enter Shikari all lined up to appear.
This is the seventh instalment of the festival, which replaced T in the Park following the Balado event ending in 2016.
