Arnold Schoenberg had the spirit of a dreamer, and in Pelleas and Melisande it takes glorious flight, with a story of doomed love set in a fairy-tale world. It is music of stirring drama and delirious beauty, drenched in orchestral colours. It鈥檚 the curtain-raiser to another Beethoven landmark 鈥� his majestic Emperor Concerto, performed by the charismatic young pianist Hannes Minnaar, who is winning major plaudits across the globe.
