Hailing from north Wales — more specifically, a tiny piece of land north of the village of Botwnnog that looks like an American prairie (hence ‘Cowboys’), Cowbois Rhos Botwnnog are a band of three brothers who peddle folk tinged with country, rock, and Americana. This year’s Green Man isn’t their first rodeo: they’ve been on the road since 2006, and we’re delighted to welcome them back.
