Founded in 1942 by Victor Desarzens, the Orchestre de Chambre de Lausanne (OCL) is today one of the most sought-after chamber orchestras in Europe. After six years under the artistic direction of the American conductor Joshua Weilerstein, the OCL is now led by the renowned French violinist Renaud Capuçon. The orchestra of around 40 musicians has a vast repertoire, from the earliest baroque to contemporary premieres. Since the 2024-2025 season, Barbara Hannigan is the orchestra's principal guest conductor.
