In February 2004, she returned to the Vienna State Opera for "Don Giovanni", and was subsequently invited as the guest performer at the Vienna Opera Ball, which she returned in 2007. She then starred in a Japan tour of "La bohème" in Robert Carsen's staging as Musetta conducted by Seiji Ozawa, and subsequently returned to San Francisco Opera in the same role. After withdrawing from "Idomeneo" in Los Angeles and "Don Pasquale" in Philadelphia, citing exhaustion from performing and promoting her album, she returned to scene in November in Metropolitan Opera's "La bohème". In 2005, she returned to Los Angeles Opera for Juliette in "Roméo et Juliette", and to the London Royal Opera in "Rigoletto". She later appeared as Violetta in the premiere of Willy Decker's new staging of "La traviata", conducted by Carlo Rizzi at the Salzburg Festival. In December 2005, she sang Gilda in "Rigoletto" at the Metropolitan Opera, and was featured in the premiere of Otto Schenk's new production of "Don Pasquale" and Japan tour of "Don Giovanni" in the same season. She returned the next year in the new Claus Guth production of "The Marriage of Figaro".
