Leonard Slatkin, who has roots in Hollywood and has conducted Rozsa before, is still music director of the DSO. Was he originally scheduled to lead this concert? The orchestra, like the city (and like many other cultural organizations), has come through a rough patch recently, but things are supposed to be looking up. I see the new program features the same soloist, concertmaster Yooshin Song, in the Prokofiev First, along with works by Strauss and Stravinsky. The conductor, Robert Treviño, is unfamiliar to me. Only twenty-five years old, he seems to be a rising star. http://www.roberttrevino.org/live/
