Well, they play a soothing mix of country, folk and rock influenced by classic rock archetypes like Dylan, Neil Young and Gram Parsons. But what will throw you off is the entire thing is done in native Welsh. So I have no idea what those lyrics mean, but the title track here, “Dyddiau Du, Dyddiau Gwyn,” has a great melodic bridge and nice steel pedal guitar work. The slow ballad “Malu’r Ffenestri” doesn’t need a lyric, as you can tell right away from its slow piano that it’s a drinkin’ tune. The song “Nansi” is a bouncey country tune that raises the spirit a bit more. The style of “Celwydd Golau Ydi Cariad” is a bit like early era Eagles with a catchy overdubbed chorus.
