Dedicated to the memory of Oliver Knussen, George Benjamin’s 2021 Concerto for Orchestra premiered at the BBC proms by the Mahler Chamber Orchestra. Benjamin said that the piece attempts “to conjure a trace of the energy, humour, and spirit” of Knussen. It is varied and dynamic across its unbroken 17-minute span — skittish lines play against still, suspended ones — and full of star turns for its various instrumental protagonists. Available here as a full score.
