Roberto Devereux is the story that centers on Robert Devereux,Duke of Essex that was executed for treason. It is not my favorite Donizetti,but its story is great. I liked John Alexander in the title role. Sets and costumes look lovely and we know that the story takes place in 1601. Richard Fredricks is powerful Duke of Nothingham,Susane Marsnee is a very touching Sara. There is one performance that captivates above all others and it is Beverly Sills as queen Elizabeth The First. Her coloratura is excellent and she sings with power and grace .She truly commands the stage and brings out all emotions of Elizabeth. Overall,amazing Wolf Trap Festival production.10/10.
