A science fiction tale with an eclectic opera scoreBefore you cast it off, know this: Angel’s Bone bears no major resemblance to Winter’s Bone, but lucky for you, it’s just as gripping. The opera follows two fallen angels who are found bruised and bewildered by a mysterious man and his wife known only as Mr. and Mrs. X.E. Though the couple nurse the duo back to health, their Good Samaritan façade has its limits. This high-octane tale of fantasy and sci-fi gets the deluxe treatment with a moving score of chamber music, pop, and visual arts. What more could you want from an opera?
