Jonas Kaufmann has canceled his upcoming performances in Paris and Aix-en-Provence.

The tenor took to social media and said, “For several months, I have been struggling with coughing and excessive mucus during my performances. This viscous secretion led to increased irritation when singing and to fatigue of the respiratory muscles. Various attempts to solve this issue were unfortunately unsuccessful, resulting in being repeatedly forced to cancel opera performances and concerts. Last week, I was diagnosed with a multi-resistant germ infection, and prescribed a high dosage of antibiotics with corresponding possible side effects. The first concert after I started taking antibiotics (Waldbühne Berlin) went surprisingly well, but since Monday the side effects, which were initially only mild, have increased so much so that I am not able to sing.”

He added, “Therefore, it will unfortunately not be possible for me to perform for the duration of the treatment, and so it is with a heavy heart that I have to cancel the two upcoming performances in Paris and at Festival d’Aix-en-Provence. Although I am very disappointed, I am glad to have finally found the cause of this persistent issue, and now I only have to give my body the necessary rest to cope with this infection, in order to be completely healthy again.”

As a result, Arsen Soghomonyan will replace the tenor at the Festival Aix-en-Provence.

Kaufmann is set to return to the stage on July 21 for a concert in Regensburg.
