Masters of Classic Festival has announced a cast change for its Sept. 7 performance.

The festival said that Joseph Calleja will perform on the stage of the Masters of Classic Festival replacing tenor Rolando Villazon, who had to cancel his concert for health reasons.

The organization added, “Despite the extremely short time, the organizer has made everything possible to ensure the audience could enjoy an extraordinary performance by the renowned tenor from Malta, Joseph Calleja.”

Calleja will perform alongside Emily Pogorelc and Michelangelo Mazza will conduct the Sofia Philharmonic at the Sala Palatului (Palace Hall).

This season Calleja returns to the Metropolitan Opera for “La Boheme” and Semperoper Dresden for “Tosca.”

Villazon returns to the stage on Sept. 11 for a performance at the  Theater Gütersloh.
