By the time Biffy Clyro take the stage in Cardiff, the room is already fully engaged. A sold-out Utilita Arena hums with anticipation, helped along by two support sets that couldn’t be more different in approach, yet together prime the crowd perfectly for the scale of what follows.

Detroit collective The Armed open proceedings with controlled chaos. Confrontational, loud and deliberately unsettling, their set is less about warming the room and more about challenging it. Vocalists roam far beyond the stage, noise levels spike without warning, and any sense of comfort is quickly stripped away. It’s not an easy watch, nor is it meant to be – but it’s effective in jolting the audience out of passive early-evening mode.

Soft Play provides the pivot point. Their stripped-back, physical punk cuts straight through the arena space, bringing focus, movement and a sense of shared release. Mosh pits open early, the duo’s crowd awareness obvious as they balance humour with sharp intent. It’s tight, loud and unpretentious, and by the time they leave the stage, Cardiff is fully switched on.

Biffy Clyro emerge to A Little Love, its huge chorus immediately met with full-voiced approval. From there, the set moves with confidence and clarity. Hunting Season and That Golden Rule hit early, bolstered by live strings that add tension and depth rather than excess. The band’s sound is expansive yet controlled, with newer material sitting comfortably alongside long-established staples.
There’s warmth woven into the middle of the set without breaking momentum. A brief, sincere rendition of Happy Birthday – sung to Naomi – draws a genuine reaction, before Friendshipping, dedicated to James Johnston and Naomi, lands quietly but with clear emotional weight. Rather than feeling indulgent, these moments humanise a show of considerable scale.

The latter half leans harder. Different People, A Hunger in Your Haunt and Black Chandelier bring bite and urgency, while Mountains sends the floor into collective motion. A stripped-back Machines briefly lowers the volume, allowing space before the closing stretch surges forward.
The final run is decisive and powerful. Living Is a Problem Because Everything Dies hits with brutal precision, Bubbles pushes things to the breaking point, and Many of Horror closes the night amid falling confetti and a room singing every word back in unison.

There’s no sense of a band trading on past glories here. Instead, Cardiff gets a focused, emotionally balanced show from a group still very much in command of their present – and more than capable of filling arenas on their own terms.
