This concert began with a posthumous premiere, the first London performance of Oliver Knussen’s Cleveland Pictures. Composed between 2003 and 2009, its short movements take inspiration from artworks in Cleveland’s Museum of Art. Seven movements were planned and four finished, plus two orchestrated fragments. A ten‐bar sketch for a sixth movement, was not included in the published score nor in this performance. It was difficult in the quarter-hour during which these graphic vignettes followed upon each other to get a sense of the whole, especially given the work’s incomplete state, but the effect was nonetheless quite often beguiling. The opening movement’s response to Rodin’s sculpture The Thinker began with soft rich string chords, cut across by loud and insistent brass gestures. Harps and bells soon joined the texture, here and often in subsequent movements, when the winds, flutes especially, added alluring detail to this palette of timbres. As befits a work based upon pictures, strands of instrumental colour seemed to be as much an organising principle as melody and harmony.
A far more delayed posthumous premiere was the fate of Britten’s Double Concerto for Violin, Viola and Orchestra, written in 1932 when he was 18. It is unclear why it was abandoned by Britten. It languished unperformed until long after Britten’s death, orchestrated by Colin Matthews for its 1997 premiere. The viola was Britten’s own stringed instrument; perhaps he abandoned his concerto because it was not in the same league as Mozart’s Sinfonia Concertante, a work he revered and for which he had learned the viola part. In the Britten, the viola often leads to delightful effect, and Lawrence Power’s large instrument made a noble sound. Vilde Frang’s violin was no less eloquent and Britten’s youthful effort, no masterpiece maybe, was worth hearing for the skilled and committed performance it received. Had the composer heard these soloists’ duetting over the pizzicato passage in the slow movement, or the virtuosity they showed in the finale, he might even have returned to his work.
