Blackbird Festival | Alter Bridge

A brand new rock festival is landing in the heart of Wales - and it's set to make some serious noise.

On Saturday 27th June, 2026, the grounds of Cardiff Castle will be shaken to their foundations as ALTER BRIDGE’s inaugural BLACKBIRD FESTIVAL bursts onto the scene with a monumental lineup the global rock heavyweights will headline. 

Launching their own festival marks a key moment for ALTER BRIDGE - not just as a celebration of their legacy, but as a bold step into curating their own live experience, bringing together a handpicked lineup of artists and connecting with fans in a whole new way.

With more than two decades under their belts, ALTER BRIDGE continue to carve their name deeper into rock history. Known for their thunderous live shows, searing dual guitars, and unforgettable melodies, the Florida-formed four piece - Myles Kennedy (vocals/guitar), Mark Tremonti (guitar/vocals), Brian Marshall (bass) and Scott Phillips (drums) - have played to millions worldwide and earned a reputation as one of the most consistent and respected names in modern rock.

Also set to perform are rising Welsh powerhouse trio FLORENCE BLACK, known for their heavy-hitting anthems and gritty, melodic swagger, and the soul-infused, arena-ready sounds of CARDINAL BLACK, whose star continues to rise at rocket speed. One more band is still to be announced, so keep your eyes locked on the lineup for a final surprise.
