Composer James Hartway, a distinguished professor of music at WSU, has written about 10 works for the harp, including several solo works and a gaggle of chamber pieces of various shapes and sizes. He\'s recently composed a concerto for not one but two harps. The piece, \"Island Dances,\" will be given its world premiere Sunday by the Arianna Harp Duo and the Warren Symphony Orchestra, conducted by David Daniels. Hartway is known for writing vibrant and eclectic music that pulsates with vernacular source material and rhythms.
