Several months ago the Kitchener-Waterloo Symphony fired music director Martin Fischer-Dieskau. But an uprising among the orchestra’s supporters won a commitment to re-hire him. After months of negotiations, though, the orchestra has decided not to rehire him. “Negotiations between Fischer-Dieskau, the symphony board and management fell apart over the weekend, with the symphony eventually deciding Tuesday evening that it could not meet with the Berlin-based conductor’s demands, which reportedly included full artistic leadership of the symphony.”
