As band-building chat-up lines go, “We’ll be your Albion Dance Band” is certainly niche. Still, it worked when US indie-rockers the Decemberists approached Olivia Chaney to form Offa Rex. They were long-term lovers of folk-rock; Chaney was a well-known collaborator but relative newcomer (her 2015 debut album, The Longest River, nevertheless gained her support slots with Robert Plant and Shirley Collins).

She has a magical voice, full of heft, soul and sunlight, reminiscent of Sandy Denny and Maddy Prior, while feeling refreshingly heartfelt and true. Add Colin Meloy’s brilliant band, and this collection of traditional songs sounds stirringly new. Take the well-known Willie O’Winsbury, or The First Time Ever I Saw Your Face: guitars, harmonium drones and Chaney’s control lift them to different places. Surprises lurk too. Lal Waterson’s To Make You Stay becomes an iridescent, piano-drizzled duet, while Sheepcrook (the Steeleye Span staple) gains brilliantly filthy, Black Sabbath rock edges. Everything works, though, loudly and proudly.
