Russian baritone Hvorostovsky cancels shows due to brain tumour

The condition has not affected Hvorostovsky's voice but "his sense of balance has been severely affected" though he is "very optimistic for the future," it said.
The silver-haired Siberian-born singer has been due to perform in Munich, Monte Carlo, as well as the Festival del Sole in California over the next two months.
Hvorostovsky, who is best known for his baritone roles in Italian operas, is still scheduled to appear in September at New York's Metropolitan Opera in Il Trovatore together with Anna Netrebko.
