The Basel Symphony Orchestra (Sinfonie Orchester Basel) is one of Switzerland's major orchestras and appears both in concert and at the opera house. The orchestra numbers among Switzerland's, leading music ensembles and has for decades produced a wide array of highlights under the baton of such conductors as Felix Weingartner, Hans Munch, Mario Venzago and Walter Weller. It's broad repertoire ranges from the Viennese classics to contemporary music. One of the orchestra's wishes came true in the 09/10 season when it's leadership was taken over by American conductor and pianist Dennis Russell Davies.
