Judith Weir wrote The Wild Reeds in 2013 for Thomas Trotter’s 30th anniversary as Birmingham’s City Organist, but there’s no pretext needed to celebrate the many extraordinary women who’ve written organ music. Judith Bingham evokes medieval art, Joanna Marsh pays delicious homage to Haydn, and Madeleine Dring simply dances for joy. And the great Jeanne Demessieux makes her own, intensely personal contribution to the French organ tradition: music to stir heart and soul.
