True, the quiet opening for high violins and viola returned to round off the third movement in a satisfying way, and the solo part, played by Heiner Herzog, showed real independence from the orchestral discourse. A composer of opera (Glyndebourne toured his Cornet Rilke a few years back) , Matthus has been compared to Britten for the facility of his ideas. There were plenty of them in here. What the work lacked, however, was a defining moment to linger in the memory.
