Bullock has sung the role in a concert version at Opera North. Given the chance of a full staging, she wasted no opportunity to show the Irish princess in all her cussed variety: angry, sardonic, petulant and eventually punch-drunk with obsessive love. She has natural vocal authority, immense colour and range and a rare power to move, which, despite a shaky start, she proved overwhelmingly in her farewell (the Liebestod).
