The Staatsoper unter den Berlin has announced that Daniel Barenboim will miss his 80th birthday celebration.

In a statement, the company said, “It is with great regret that Daniel Barenboim for health reasons has to cancel the concert planned on the day of his 80th birthday on November 15, together with Zubin Mehta and the Staatskapelle Berlin. We hope to be able to make up for the concert at a later date.”

The company added, “Intendant Matthias Schulz, Managing Director Ronny Unganz and all staff members wish Daniel Barenboim all the best and a very speedy recovery!”

The Berlin opera is inviting audience members to send Barenboim birthday wishes by sending messages until Nov. 10 to [email protected]. The company will collect them and hand them over to Daniel Barenboim on his birthday on Nov. 15.

The news comes after Barenboim announced he would be stepping back from performing after being diagnosed with a serious neurological condition.
