Joyce El-Khouri broadened the heart-on-sleeve histrionics with her sinuous, intelligent portrayal of Antonina...El-Khouri sang wonderfully, producing a penetrating pianissimo of exceptional tonal solidity and dealing with all the bel canto gymnastics with effortless technical security. Her sexy and imperious presence cast a long, interesting shadow over the whole evening, and she was electrifying in her confession of perjury that closes the opera.
