Dutton Epoch’s pioneering issue of unrecorded Delius conducted by David Lloyd-Jones includes Delius’s early tone poem Hiawatha in Robert Threlfall’s performing version. It proves to be a considerable find, the link between Florida and Paris winningly played by the BBC Concert Orchestra in their world premiere recording. It comes in a programme of concertos brilliantly performed by violinist Philippe Graffin and Sarah-Jane Bradley (viola). The principal work is the eloquent Lionel Tertis arrangement for violin and viola of the Double Concerto, in a world premiere recording that was recorded (Watford Town Hall) less than a mile from where it was written. Delius’s early Suite for violin and orchestra and the Legénde for violin and orchestra here receive only their second recordings, and are brilliantly projected by Philippe Graffin. The programme is rounded off by Sarah-Jane Bradley’s cherishable reading of the viola version of the Caprice and Elegy. It all adds up to an unmissable and unique survey.
