Dessay's 2006/2007 season schedule included Lucia di Lammermoor and La sonnambula in Paris, La fille du régiment directed by Laurent Pelly in London and Vienna, and a Manon in Barcelona. She appeared in two new productions during the 2007–08 season at the Met: as Lucia on opening night, and in a reprise of the London production of La fille du régiment .  In January 2009 she sang the part of Mélisande in a much acclaimed production of Pelléas et Mélisande by Claude Debussy at the Theater an der Wien , Vienna's second world-class opera house, alongside Laurent Naouri. On 2 March 2009, Dessay sang the title role in La sonnambula at the New York Metropolitan Opera . It was the first new production of the opera at the Met since Joan Sutherland sang the title role in 1963.
