Do explore this fascinating and rewarding programme, brilliantly played by the Royal Scottish National Orchestra. Here conductor Martin Yates heads his selection with Richard Arnell's Sinfonia - effectively his 'Symphony No.0' - which was long thought lost. When Arnell's daughter arrived from the USA in 2009 to attend her father's funeral she revealed that she had found this score among the papers of her late mother in Lincoln City, Nebraska. Martin Yates has now edited the music for performance, and it makes an essential contribution to Dutton Epoch's pioneering Arnell cycle. It is coupled with a long, dramatic, symphonic movement written in New York early in 1940, which the composer called Overture '1940', Op.6. Back in London after the war, Arnell was very active. He produced a suite - the so-called Dagenham Symphony - in 1952. This is very approachable film music, ending with a catchy march, music to which the documentary Opus 68 was actually shot. Four years later came Landscapes and Figures - eight short movements with enigmatic titles playing continuously. Arnell tells us that this attractive music had its origins in visual imagery, and it is in his most persuasive mature vein, with memorable invention and brilliant orchestration. "Landscapes and Figures should soon find a home in the ballet theatre," wrote one critic after the first London performance, and one can only agree that such lyrical and immediately communicative music would have been (indeed still might be) supremely effective. Here are four really worthwhile revivals that add materially to our enjoyment and appreciation of Arnell's output. If you have the earlier titles in Dutton Epoch's Arnell series, this is an essential programme. For those coming new to Arnell, it is a great place to start. World premiere recordings.
