Thomas Hampson has cancelled his upcoming performances with the Orquestra Simfònica de Barcelona.

The Baritone was originally scheduled to perform Mahler’s “Des Knaben Wunderhorn” on Dec. 16, 17 and 18.

Hampson announced the news on Twitter and stated,  “Very disappointed that I must cancel my upcoming concerts in Barcelona. I’m suffering from a viral tracheitis that makes singing impossible.”

However, he noted that he will try to make it up on another date. He said, “How I would have loved to perform Mahler’s “Des Knaben Wunderhorn” in Barcelona. I very much hope to make it up to you very soon.”

In recent years Hampson has become specialized in Mahler song cycles in particular “Des Knaben Wunderhorn.” He recorded the work with the Wiener Virtuosen to celebrate the composer’s 100th birthday and that recording garnered numerous accolades and received rave reviews.

Hampson recently sang the four villains in Offenbach’s “Les Contes D’Hoffman” with Vittorio Grigolo and Sonya Yoncheva at the Royal Opera. The performances were recorded live in HD and brought to cinemas around the world. The baritone next sings a concert with Luca Pisaroni entitled “No Tenors allowed” and reprises his role as Roald Amundsen in the work “South Pole” at the Bayerische Staatsoper. He also sings the role of Scarpia in Puccini’s “Tosca” at the Vienna State Opera and also returns to the Metropolitan Opera to sing Giorgio Germont in Willy Decker’s production of Verdi’s “La Traviata.” He sings the production he first premiered in 2005 alongside Sonya Yoncheva and Michael Fabiano. Later this season Hampson brings his famed Don Giovanni to La Scala in Milan for the first revival of Robert Carsen’s 2011 production.

The Barcelona concerts are still scheduled for Dec. 16, 17 and 18. Dietrich Henschel will replace Hampson and Kazushi Ono will conduct the program that also includes Shostakovich’s Symphony No. 6.
