Robert Saxton - Viola Concerto.  City of London Sinfonia - Hickox  Royal Albert Hall London :: BBC Proms :: August 1993 The Times - Noel Goodwin (The concerto draws) the most reticent of orchestral instruments into the spotlight, and Paul Silverthorne, for whom it was written, proved himself a virtuoso in sensitivity and technique. The Guardian - Edward Greenfield .. it was welcome that Robert Saxton's Viola Concerto was so compact in its four sharply conceived and well-balanced movements. Paul Silverthorne was the masterly soloist, finding lyricism even in some of the grittiest string writing.
