Since 1922 this orchestra has achieved world acclaim with music directors such as Seiji Ozawa, Sir Thomas Beecham, and Sir Andrew Davis. Canadian-born Peter Oundjian helped return the ensemble to an international level when he took over as musical director in 2003. Guest performers have included pianist Lang Lang, violinist Itzhak Perlman, and singer-songwriter Rufus Wainwright. Each season the orchestra screens a classic film, such as Casablanca or West Side Story, and
plays the soundtrack as it runs. The TSO presents about three concerts weekly at Roy Thomson Hall from September through June.
