TRNSMT swelters with Biffy Clyro headlining day two of festival

Music fans have sweltered on another day of soaring temperatures at TRNSMT festival in Glasgow.

Biffy Clyro headlined the Saturday bill, with Underworld and a secret set from singer-songwriter Amy Macdonald also on the day two line-up.

The mercury reached 29C in the city, with health officials urging fans to stay hydrated and use suncream during the heatwave.

Irish rock band Fontaines DC walked onstage to a song from Kneecap - the rap act controversially dropped from TRNSMT earlier this year - before leading the crowd in "free Palestine" chants.

The political statements continued with pro-Palestinian messages on the stage video screens, while during the song I Love You another message appeared accusing Israel genocide in Gaza.

The band have previously been supported by Kneecap at previous shows.

Headliners Biffy Clyro then delivered a typically sweaty performance that included plenty of pyrotechnics, as well as confetti shooting over the crowd.

Bassist James Johnston joked that the group were dedicating the song Different People "to the gingers, for surviving" in the day's heat, as they played through a career-spanning set.

Earlier a packed crowd had gathered at the Hangout tent for a performance by an artist listed as Ms Rock n' roll - a reference to Amy Macdonald's hit Mr Rock n' Roll.

She played material from her new album Is This What You've Been Waiting For, which was released on Friday, including opening with the record's title track.

Afterwards she joked that the tent was so packed she was worried one of her friends wasn't going to be able to even get in

Macdonald told BBC Scotland News that the festival was vital to helping new Scottish music, as well as established acts like the evening's headliners.

She said: "What's great is that they give Scottish artists a chance that they might not get at other festivals in the UK.

"It's always nice to see so many other up and coming Scottish bands get the chance, and promote the new generation."

Police Scotland said there had been six arrests on the festival's first day on Friday, for offences including police assault, hate crime and outstanding warrants.

Saturday's early highlights included Norwegian singer Sigrid, who donned a tartan TRNSMT football top during her set of synth-pop.

Irish rock band Inhaler offered a more straightforward display of rock n' roll, with bassist Robert Keating saying the group felt like they "were in the home of guitar music".

Arguably the most impressive achievement was Inhaler singer Elijah Hewson managing to wear a parka despite the scorching conditions.

Although a breeze meant heat on the site was less stifling than Friday, many fans headed for shaded sections away from the sun, particularly at the smaller stages.

A change to the Saturday bill - announced on Friday - saw rock band Wunderhorse drop out due to illness. They were replaced by singer-songwriter Miles Kane.

Festival stewards told BBC Scotland News the event felt like the hottest event they'd ever worked in Scotland.

Fans sprawled on the grass during folk band Amble's laid-back set, with the band themselves admitting they were roasting as they performed.

Dr Emilia Crighton, NHS Greater Glasgow and Clyde's director of public health, said fans should take care of each other as "the heatwave has now well and truly arrived."

She added: "For those attending TRNSMT in Glasgow, we would continue to ask festival goers to look after themselves and others so everyone can enjoy themselves safely.

"Sunscreen is available from first aid tents and we'd remind people to keep hydrated."

The first day of the festival saw 50 Cent top the bill, while indie rock band Wet Leg referenced the war in Gaza and Scottish singer Calum Bowie opened the main stage.

The event on Glasgow Green concludes on Sunday with a headline performance from Snow Patrol.
