Aimee Wilson’s new album is inspired by the Sacred Harp, a Protestant tradition of unaccompanied vocal singing that can be heard here in its uncut form in the traditional “Detroit”. The other songs here are her own, and the Sacred Harp singing is set against the playing of her band, including hurdy-gurdy and Chinese erhu, and Wilson’s own singing, thick, quivering in ecstasy and utterly committed. (4/5 stars)
