Bitw’s “Hen Dro” takes the familiar subject of a relationship on its way out and places it within the framework of a notably darker album. On the surface, it might read as a straightforward pop song about doomed love, but that surrounding atmosphere gives the material a more melancholic edge. Mari returns on backing vocals, joined by Gwion Llewelyn, with Stephen Black on saxophone. “Hen Dro” explores the contrast between recognizable pop subject matter and the darker world around it.
