Founded in 1942 by Victor Desarzens, the Orchestre de Chambre de Lausanne (OCL) has become one of the most sought-after chamber orchestras in Europe. After six years under the artistic direction of American conductor Joshua Weilerstein, the OCL is now led by the celebrated French violinist Renaud Capuçon. Comprising some forty musicians, the Orchestra’s vast repertoire ranges from early Baroque to contemporary works.

The OCL was soon invited to perform abroad, in the most renowned concert halls and festivals. It took part in the second Aix-en-Provence Festival and several editions of the Enescu Festival in Bucharest. His tours of Germany and the United States have been resounding successes, as have his concerts at the Théâtre des Champs-Élysées in Paris, the BBC Proms in London, the Wiener Konzerthaus and the Berliner Philharmoniker. In the 2023-2024 season, the OCL will perform in Madrid, Barcelona and, for the first time, at the Philharmonie de Paris.

Throughout its existence, the OCL has performed with leading soloists. These include Clara Haskil, Alfred Cortot, Walter Gieseking, Edwin Fischer, Murray Perahia, Radu Lupu, Martha Argerich, Nikolai Lugansky, Daniel Barenboim and Frank Peter Zimmermann. The OCL has also always attracted the most interesting conductors of their time, including Paul Hindemith, Günter Wand, Christoph Eschenbach, Ton Koopman, Jeffrey Tate, Bertrand de Billy, Simone Young and Daniel Harding.

The OCL boasts an extensive discography: from the complete operas of Haydn in the 1970s-1980s conducted by Antal Dorati to the Beethoven and Mozart concertos with Christian Zacharias, not to mention recordings dedicated to Schoenberg and Webern (with Heinz Holliger) and Spohr and Weber (with Paul Meyer).
