OK, so this is not earth-shattering stuff but... I started to wonder if I was listening to the same CD as the guys who wrote the other two reviews.
Personally, I think the Guardian review got it about right - this is lyrically well-crafted, well played, well-produced and, most importantly, beautifully sung material at the more baroque, exploratory end of the current folk-pop spectrum. (And it doesn't take itself too seriously). Best enjoyed for its own sake, maybe, rather than on the basis of who else it might or might not sound like?
