DADLEOLI

Dadleoli are a Welsh band who have already broken ground as one of the most promising names on the scene. The summer of 2025 included performances at Tafwyl, on the main stage at Sesiwn Fawr Dolgellau, Llwyfan y Maes and Maes B at the Wrexham National Eisteddfod 2025. Playing Indie Rock music, their sound is energetic and modern. The band members are Efan Williams, Jake Collins, Caleb Griffiths, Tom Spivey and Jac Cordery.

Formed back in 2022 in Cardiff under the guidance of Mei Gwynedd, the band have quickly built a reputation for their live performances and released the EP ‘Diwrnodau Haf’ in 2023 and the album ‘Fy Myd Bach i’ in 2024. Both have attracted attention on the scene and tracks have received regular radio play. The track ‘Haf i Ti’ was also used as S4C’s anthem for their summer gigs campaign.
