Metamorphosis, an Edmonton-based chamber orchestra, has had a good first season after being born from the ashes of the relationship between the Edmonton Symphony musicians and their management. Grzegorz Nowak, the conductor who was deposed from the symphony’s music directorship only to announce that he would stay in town and start his own orchestra, has backed off his original brash plans of competing directly with his old employer, and crafted a much-needed niche ensemble. In fact, starting next season, the smaller group, which will be renamed the Canadian Chamber Orchestra, will be playing its concerts at the same hall occupied by the Edmonton Symphony.
