The Los Alamos Community Winds, now numbering 49 players, undertook a major work Sunday at the Betty Ehart Senior Center for a near-capacity audience: an arrangement for band of the Dvork “Symphony No. 9, Op. 95,” under the direction of Ted Vives. Extensive program notes were provided: three pages on the Dvork and three more on the four short numbers.After a prolonged tune-up period, which was not entirely successful, the four movements of the Dvork were performed without interruption.
