Dutch violinist Janine Jansen, a former BBC New Generation Artist and a regular visitor to the Barbican, applies her nimble technique and elegant interpretative skills to Mendelssohn’s high-spirited Concerto, which never loses its freshly-minted appeal. Daniel Harding introduces a new work by the brilliant young composer Edward Rushton, while Mahler’s glorious Fifth Symphony, containing in its sublime Adagietto for harp and strings and one of music’s most passionate love-letters, rounds off this entrancing programme.
