Swn Fest is the brain-child of Radio 1 supremo Huw Stephens, who last year put on a great collection of bands in Cardiff, including The Cribs, Black Lips, Beirut, as well as the best, freshest new music Wales has to offer. There are few people better qualified for this job than Huw, who presents the ‘Unsigned’ show, and here he is doing it all again. For those non-Welsh speakers amongst you, ‘Swn’ is Welsh for sound. Don’t say we never teach you anything.
