Camarena is fine - he and Rucinski impress me most - but I can do without Sierra. I don't find her timbre especially beautiful or distinctive, and she sings with little nuance. I get no sense of a character from her, no suggestion of a girl who would lose her mind and commit murder. In fact everybody in this production is rather relentlessly loud. Is it because they're in the American rust belt that they all think they have to belt?Rucinski is totally superb but so, my dear, is Nadine Sierra. Lord she has a beautiful voice and knows how to use it. I have always liked Camerena's voice. It is such a wonderful gift to listen to these beautiful voices sans il sangue.
