What we hear from the Canadian singer, perfectly at ease with the vocal poetic language of Italian romanticism, deserves more than respect. From her entrance aria to the great final scene immortalized by Callas [ ] Joyce El-Khoury holds herself consistently at the highest level of vocal and musical quality. To her aerial vocalism and her long Bellinian legato lines, she adds here a surprising foundation in the lower register, so often appealed to in this opera. It is a triumph largely deserved she receives at the bows.
