If you thought the accordion was just a squeeze box, then James Crabb is the man to change your mind. His playing combines technical brilliance with exquisite musical sensitivity and in his hands, the instrument’s place in the orchestra feels completely natural. Put him alongside Sinfonia Cymru’s highly-talented young players, in a programme that includes Piazzolla, Vivaldi and Arvo Pärt and you have a recipe for sheer musical enjoyment.
