The Seattle Symphony has decided not to appeal a court ruling ordering it to settle a lawsuit brought by its recently dismissed concertmaster through arbitration. Violinist Ilkka Talvi, who recently turned up the heat on the orchestra by launching a blog and using it to air much of the ensemble’s dirty laundry, claims that he was capriciously dismissed by Seattle music director Gerard Schwarz, and further argues that a clause in his contract does not allow him to be fired so long as Schwarz remains in charge.
