The Baltimore appointment may mark the first time Marin Alsop will have full control of a major American orchestra, but she’s no stranger to the prestigious podiums of the world, and musicians from some of the world’s best ensembles are going out of their way to support her in the wake of the Baltimore controversy. This past weekend, a violinist in the London Symphony stood at the end of a rehearsal to praise her and wish her well in her new job, prompting hearty applause from the entire LSO. Everywhere, the hope seems to be that Alsop’s famous charisma will win over the Baltimore musicians who tried to stop her appointment as a protest over what they viewed as an aborted music director search process.
