Lubin had a powerful voice of gleaming tonal splendour. By her own admission she was a forceful and demanding personality, often haughty and distant with other people, and she responded to the heroic dimension of the characters that she portrayed on the operatic stage. "I do not like to sing the role of victims", she said in an interview."Mais je n'aime pas chanter les victimes". In an interview given to Le Quotidien de Paris on 10 July 1974, reproduced in Altamusica.
