Music review: Cumnock Tryst Festival, various venues, Cumnock

Something special happened on Saturday evening. It was the centrepiece of this year’s Cumnock Tryst – a programme that fully embraced the ethos of the festival founded five years ago by the Ayrshire town’s local-boy-done-good, Sir James MacMillan, set out by the composer as a means of drawing together the international stars of the classical music firmament, the ordinary people of the burgh, its modest venues and the functional and inspirational application of his music.
