Robbie Williams turned day two of Bilbao BBK Live 2026 into a two-part set when he ran on stage during CMAT's slot after headlining the main stage earlier that night. CMAT then led the crowd in a singalong of Angels before Williams hugged her, and the exchange landed as the night's sharpest live-music crossover.
CMAT said, “I really know that it seemed like that was planned, but it really wasn’t.” That line matters because it separates a neat festival narrative from the actual sequence on the ground: a headliner finishing one set and then reappearing as a guest in another artist's show on the same night.
Bilbao and day two
Bilbao BBK Live 2026 kicked off on Thursday, July 9, which put Williams and CMAT into the event's second day. The structure of that booking made the surprise possible: one artist had already played the main stage, while CMAT was still on the Repsol stage later in the programme.
CMAT, the Dunboyne singer whose real name is Ciara Mary-Alice Thompson, has had a run of visible moments around Euro-Country. Back in May she took home the Best Album award for the record at the Ivors 2026, and earlier in 2025 it was shortlisted for the 2025 Mercury Prize.
Angels in the set
CMAT led the crowd in a singalong of Angels before Williams appeared, and the audience response was immediate enough to turn the moment into the night's loudest beat. That kind of handoff between one performer and another is rare at a festival line-up built around separate slots, because it collapses the usual distance between headline billing and guest appearance.
Williams' walk-on also connected to the wider arc around CMAT's recent run, which has included attention for Take A Sexy Picture Of Me and the cover of When A Good Man Cries by Olivia Rodrigo on Radio 1's Live Lounge. Rodrigo called CMAT “such an incredible, unique songwriter,” and the coverage around that performance helped push her further into the mainstream conversation.
Friday, July 11
Bilbao BBK Live 2026 was set to continue on Friday, July 11, with closing sets from Lily Allen and IDLES. For anyone tracking the festival's momentum, the Williams-CMAT moment is the sort of unplanned crossover that gives a bill extra heat without changing the formal line-up.
The open question is straightforward: whether Robbie Williams and CMAT will build anything beyond this surprise on-stage moment has not been answered, and that is the point worth carrying forward. For now, the night belongs to the hug, the singalong of Angels, and CMAT's insistence that the whole thing was not staged.
