Sawallisch died late Friday at his home in Grassau, upper Bavaria, the opera said in a statement. \"The Bavarian State Opera is deeply saddened by the death of Wolfgang Sawallisch,\" said the opera\'s current chief Nikolaus Bachler. \"For decades, he left his stamp on our house with his great personality and his inimitable art. His name, like no other, is connected with the Munich opera and even today his influence can still be felt,\" Bachler said. A gala performance scheduled for Monday of Giuseppe Verdi\'s \"Requiem\" by the Bavarian State Opera orchestra and conducted by Indian-born maestro Zubin Mehta would be dedicated to Sawallisch\'s memory, he added.
