Major US artist to headline huge outdoor gig in Cardiff Castle

The Depot in the Castle headliner for 2026 has a massive fan in President Barack Obama

American singer-songwriter Ethel Cain will headline Depot in the Castle 2026. The artist will perform at Cardiff Castle on Friday, June 19.

The date sees Cainextend her sold-out Willoughby Tucker Forever tour into 2026 adding dates across the UK and Europe.

Presale tickets are available at 10am Wednesday via depotlive.co.uk and all tickets go on general sale at 10am Friday via depotlive.co.uk and ticketmaster.co.uk.

The announcement comes ahead of Cain’s sold-out 2025 UK/EU tour dates which kick off next Thursday at Manchester’s O2 Apollo and will see her headline five nights at London’s Eventim Apollo.

Cain is the alter-ego of Florida-born multidisciplinary artist Hayden Anhedönia. After years spent teaching herself to produce at home in the Florida panhandle and releasing various projects, Cain moved to Indiana and singlehandedly wrote, produced, recorded and mixed her acclaimed 2021 EP Inbred from the basement of the old church where she lived.

Their Willoughby Tucker Forever 2025 tour dates sold out completely when they went on sale in March, with 170,000 tickets sold in just a few weeks, and Cain recently extended her run of Australia and New Zealand dates due to phenomenal demand.

Earlier this month, Cain wrapped the US leg of the tour and was announced for Coachella 2026. President Barack Obama also recently added the artist to his much-sought after playlist.

DEPOT Live promoter Nick Saunders said: “Announcing Ethel Cain is coming to Cardiff is a coup for us. This tour has sold out globally so we are delighted to have secured a date here at the Castle for summer 2026. This will be a very special show.”
