The Biel Solothurn Symphony Orchestra (Sinfonie Orchester Biel Solothurn / Orchestre Symphonique Bienne Soleure) was founded in 1969 and has since gained an important place within the Swiss music scene. It is based in the Swiss cities of Biel-Bienne and Solothurn. Heavily influenced by Swiss conductors Armin Jordan and Jost Meier in its beginnings, the orchestra has been directed by Kaspar Zehnder since the 2012/2013 season.
Central to the ensemble’s artistic work are the symphonic concerts in Biel and Solothurn. While never neglecting the important works of the classical repertory, a special emphasis is placed on works from the 20th century and contemporary music; numerous orchestral compositions and operas have seen their first performance by this orchestra.
Next to the symphonic concerts and its participation in the operatic productions of the Theater Orchester Biel Solothurn, the orchestra presents annual summer concerts which take place under the open sky and feature young musicians in training from all over the country.
