Okay, this is one of those good-news-bad-news posts, except that the bad news isn't that bad. Patricia Kopatchinskaja, who had been scheduled to be Ojai's music director for 2020, will instead be the music director for 2018. This is neutral; we get this talented violinist and new music advocate sooner!
The bad news is that Esa-Pekka Salonen was supposed to the MD in 2018, and he has withdrawn from that year. The embedded good news in Salonen's withdrawal is that his composition schedule is the cause. More music by Salonen is an unalloyed good thing.
