Musical honours of the dance week go to the young pianist Jason Ridgway, playing dazzlingly intricate Scarlatti sonatas on stage as part of Martin Lawrance's Grey Allegro, receiving its British premiere at The Place. Using dancers from Richard Alston's company (to which Lawrance belongs), the piece offers a crisp visual counterpart to the fingeriness of the music, as well as its formal devices, yet also hints at a vestigial emotional narrative that keeps you on the edge of your seat.
