British conductor John Wilson has long been a Proms favourite, but last year’s debut appearance of his new super-orchestra the Sinfonia of London caused a sensation. ‘Astonishing,’ wrote The Times. For The Spectator, this was ‘an orchestra so thrillingly alive with the sheer glory of it all that hearing them play felt like being a teenager in love’. Now Wilson and the Sinfonia are back, in an all-British programme that pairs much-loved classics by Elgar and Vaughan-Williams with Walton’s kaleidoscopic Partita, Bax’s stirring musical seascape and Huw Watkins’s spirited Flute Concerto, played by its dedicatee Adam Walker.
