A regular at the Proms since his debut here over a decade ago, former BBC Young Musician of the Year Benjamin Grosvenor brings a selection of transcriptions and arrangements of works better known in other guises. The sensuality of Debussy’s Prelude a l’apres-midi d’un faune melts into Ravel’s tender Le tombeau de Couperin suite and his heady, war-scarred La valse, while a passing visit to the Italian opera comes courtesy of Liszt’s virtuosic reimagining of Bellini’s Norma, a bel canto tale of warring Druids and Romans, set in ancient Gaul.
