(Minneapolis, MN) -- Minnesota Orchestra conductor Osmo Vanska (OZZ'-moe VAHN'skuh) has resigned as a labor impasse between management and the musicians drags on. The lock-out began one-year ago today, and the latest contract proposal was rejected over the weekend. Tim Zavadil with the Minnesota Orchestra musicians says Vanska made it known that if the upcoming Carnegie Hall concerts in New York were canceled, he would resign. He says the Carnegie performances were a dream of Vanska and to see the rug pulled out from under it is "just incredibly sad." Vanska was credited with raising the orchestra's reputation to one of the world's best. He called it a "very sad" day.
