Extolled worldwide as a foremost interpreter of Rachmaninov’s music, Boris Giltburg offers Ryedale audiences a chance to hear his rarely performed first sonata, a work of stupefying virtuosity that evokes a titanic battle between good and evil (containing a wonderful tune with pre-echoes of Paul McCartney’s Yesterday), before turning to the much-loved Preludes that Rachmaninov composed in a mood of creative elation.
