La muette de Portici
To begin her career she made a concert tour which took her to Brussels. Her concert was so successful, that Count de Liederkerke offered her a contract to sing operatic roles. Although she had not previously considered performing in dramatic works, she agreed, as Cassel would coach her for six months to prepare her for singing and acting on stage. She made her debut in 1825 at the Théâtre de la Monnaie in Brussels. In 1829 she performed Elvire in the first Brussels performance of Auber's "La muette de Portici" and repeated the role in the notorious performance of 25 August 1830 which precipitated the Belgian Revolution.
