A TOP music festival will mark its 50th year with the world premiere of a new work to celebrate its illustrious history. The piece written by Jon Guy will be featured in one of two concerts in May which will be curtain raisers for the North Wales International Music Festival which in normal times is held at St Asaph Cathedral. Like the main event last September, the concerts will be staged online – with the premiere of the music called Shining Dawn happening at 7.30pm on Saturday, May 8. At the same time the day before, the globally-renowned choir Tenebrae will be delighting the festival audience.
