Mere weeks after extending the contract of music director Gerard Schwarz, the Seattle Symphony has been thrown into chaos amid what appears to be an open revolt against Schwarz’s leadership. Executive director Paul Meecham, whose tenure got off to a rocky start a few years back when he suggested that the SSO might need to look beyond Schwarz, has resigned, and the orchestra’s musicians are preparing to publicly release an internal survey expressing widespread dissatisfaction with Schwarz’s leadership. One well-respected musician who recently questioned Schwarz’s extension in a letter to a local weekly has also been tagged for dismissal from the SSO in what the musicians say is an obvious act of retaliation.
