Conductor Kent Nagano is suddenly the man of the moment. “Nagano, 52, was in the news last month when the Montreal Symphony Orchestra put an end to weeks of rumors and officially announced that he would become the orchestra’s music director starting with the 2006-07 season. In February, the Bavarian State Opera named him to succeed Zubin Mehta as general music director, also beginning in 2006-07. He is currently music director of the Los Angeles Opera, Berlin’s Deutsches Symphonie-Orchester and the Berkeley (Calif.) Symphony Orchestra, a post he has held for more than 25 years.”
