Orchestras are not in the habit of telling conductors how to do their jobs – it’s supposed to be the other way around. But with Yakov Kreizberg stepping in at the last minute to fill in for the ailing Wolfgang Sawallisch on the Philadelphia Orchestra’s South American tour, the orchestra has taken the unusual step of asking the maestro to tone down his ‘antics’ on the podium, and to leave the tempos where Sawallisch put them. Kreizberg, by all accounts, has taken the chiding in stride, and Peter Dobrin says that the unusual talking-to seems to have done some good.
