Joseph Kaiser is withdrawing from the opera business.

The Theater an der Wien announced that the tenor has canceled all opera engagements including his two previously scheduled performances with the company this season due to personal reasons. The Theater an der Wien is one of the major theaters to be affected by Kaiser’s decision as the Royal Opera announced last month that Kaiser had withdrawn from an upcoming production of R. Strauss’ “Salome.”

As a result, the Theater an der Wien announced that Jeremy Ovenden will replace Kaiser in Mozart’s “La Clemenza di Tito” while Eric Cutler will sing the role of Florestan in “Fidelio” replacing Kaiser.

Ovenden is a British tenor who has performed in Brussels, Edinburgh, Toulouse, and Madrid. Meanwhile, Cutler has performed at the Metropolitan Opera, Opéra National de Paris, Salzburg Festival, Glyndebourne, and Bayerische Staatsoper, among others.

“La Clemenza di Tito” opens on Oct. 17, 2019 while “Fidelio” opens on March 16, 2020.
