Composer-conductor-performers Across the centuries leading musicians, at home and abroad, have demonstrated their versatility in fulfilling dual roles as composers-conductors, conductor-performers or performer-composers with great success. In today's Afternoon on 3, Louise Fryer celebrates the accomplishments of figures who have met these criteria, including Sir Hamilton Harty, Charles Villiers Stanford, Felix Mendelssohn and the contemporary British conductor-composer Stephen Barlow - all in recordings by Ulster Orchestra.
