Biffy Clyro Headline TRNSMT Amid 29C Heatwave in Glasgow

The TRNSMT 2025 music festival in Glasgow featured headliner Biffy Clyro, who delivered an energetic and well-received set including hits like 'Mountains' and 'Many of Horror' amid a heatwave with temperatures reaching 29°C. The band, returning after a five-year absence, played both classic and new songs, captivating a crowd of 50,000 attendees. Scottish newcomers The Rooks also made their festival debut without a record deal, highlighting their hardworking ascent in the music scene. Alongside Biffy Clyro, other acts such as Fontaines DC performed, though their inclusion stirred controversy due to political comments and security concerns. Festival organizers and health officials urged attendees to stay hydrated and use sun protection during the soaring temperatures. Police reported a few arrests on the festival's opening day for various offenses, but the event continued successfully with enthusiastic crowds.
