Three Swiss premieres, students from the HEM Genève-Neuchâtel mixed with professionals under the direction of a great master composer: the concert on Wednesday evening at the Victoria Hall in Geneva looked like a high mass. Appreciated by a mixed-age audience, Peter Eötvös and the many musicians gathered on the stage have fervently served contemporary creation. A river evening playing on the synergy of four institutions: the Ensemble Contrechamps, the HEM Genève, the OSR and the Festival Archipel.
