Notable was the level of technical accomplishment in works conceived in diverse styles and mostly produced by a younger generation of composers. Premiered as the final concert’s centrepiece, Edmund Finnis’s Seeing Is Flux takes its title from the American novelist Siri Hustvedt, its layered textures and ambiguous blend of innocence and sophistication demonstrating a keen ear for sonority skilfully deployed throughout a neat and effective structure; conductor Baldur Brönnimann held its iridescent surface up to the light in what proved to be a compelling reading.
