Thursday 23 April – Alex Warren (with Claire Rosinkranz) Kicking things off is American singer and YouTube star Alex Warren, whose breakout ballads “Chasing Shadows” and “Before You Leave Me” have propelled him from social media fame to an international headlining tour. He’s joined by Californian alt-pop name Claire Rosinkranz, best known for the TikTok-favourite “Backyard Boy”. Expect a night of melodic, emotional pop with a fiercely loyal Gen Z crowd. Friday 24 April – YUNGBLUD (with The Warning) Yorkshire’s own YUNGBLUD brings his trademark high-voltage energy and boundary-pushing sound back to the capital. His 2026 world tour has been hyped as his biggest production yet, blending punk-rock chaos with heartfelt anthems. Support comes from Mexican rock trio The Warning, fresh from their recent festival circuit acclaim. Saturday 25 April – Rick Astley (with Gabrielle) Saturday night is pure nostalgia, as Rick Astley continues his astonishing live resurgence. The “Never Gonna Give You Up” singer has evolved into one of the UK’s most reliable crowd-pleasers, trading in feel-good hits and wry humour.
