Glasgow Green belonged to Biffy Clyro. The Scottish rock trio, Simon Neil alongside twins James and Ben Johnston, headlined TRNSMT Festival on home soil and turned it into a full-blown homecoming celebration. The set moved between jagged, complex riffs and stadium-sized choruses, with a massive crowd roaring back every word. Neil and company affirmed their place among the UK’s most formidable live acts, opening with the explosive one-two of “The Captain” and “That Golden Rule” before charging through a career-spanning run of fan favorites. They flexed serious range too, from the raw power of “Wolves of Winter” to a tender “Re-Arrange” and Neil’s stripped-back acoustic take on “Machines.” The production matched the ambition, with bagpipes and confetti erupting during “Stingin’ Belle” and fireworks lighting up the closing anthem “Many of Horror.” This was a band at the absolute peak of its powers.
