Osmo Vänskä has said that he will resign from the Minnesota Orchestra if the current crisis is not resolved by Sept. 9. The latest news suggests that a resolution is not imminent. Will the Minnesota board be unhappy if Vänskä leaves? Norman Lebrecht thinks not. The group Orchestrate Excellence will host a community forum tomorrow, seeking to preserve the orchestra as a world-class ensemble. The speaker will be Alan Fletcher, whose convocation address at Aspen is worth re-reading with care. His most important thought: "Include musicians at the heart of decision-making."
