Costume designer Arkadius has decked out his principals — the heroines and their swains who occupy the Don during the course of the opera — in a consistent color scheme: paired yellows for the bumpkin lovers, formal black-and-green for the nobles, a rich, mournful blue for the jilted Elvira. The period is Mozart’s own, wildly exaggerated with the women’s gowns on panniers nearly as wide as the stage itself. The musical matters, under the excellent German conductor Hartmut Haenchen, accomplish much the same for the ear. Uruguay-born Erwin Schrott returns as Giovanni, lithe, insinuating, menacing with a voice of similar character. The women who bring about his downfall form a first-class ensemble: Alexandra Deshorties as the majestic if somewhat frazzled Anna, Maria Kanyova as an Elvira totally unhinged in the clash of love vs. hate. As the comic servant Leporello, Kyle Ketelsen delivers some expert and hilarious footwork, with singing to match. Stylistically, in fact, both servant and master seem adrift in a whole 'nother opera — the one by Mozart.
