What makes for a memorable performance at the festival? How about a performance by Suzanne Corey-Sahlin and Gerald Steichen, principal violist and musical director of the Ridgefield Symphony Orchestra, respectively. Now approaching its 50th anniversary, the RSO is a fully professional orchestra with a rich history. Under the direction of Gerald Steichen, the RSO consistently presents top quality performances to rave reviews. Their programming includes well known classics, exciting contemporary music and lighter fare for orchestra newcomers. It was a pleasure to feature their performance of Rebecca Clarke’s Viola Sonata.
