Two months ago, Paul Meecham abuptly resigned as CEO of the Seattle Symphony amid a firestorm of controversy concerning the orchestra’s music director, Gerard Schwarz. He wasn’t out of work long: this week, the Baltimore Symphony tapped him to be their next top executive. The BSO has had a few controversies of his own over the past couple of seasons, and the hope is that Meecham can bring badly needed stability to an organization that has seen little of it recently.
