Franz Welser-Möst will retire as music director of the Cleveland Orchestra in June 2027, ending a 25-season tenure that will be the longest in the ensemble's history.
The orchestra said in September that the 63-year-old had a cancerous tumor removed and he was canceling conducting performances from late October through the end of the year. At the time, the orchestra said he would undergo treatment between conducting engagements for 12 to 16 months.
