Chamber concerts during the coming Festival summer feature members of the Vienna Philharmonic in a programme commemorating the founding of the International Society for New Music (IGNM). It was founded in 1922 – at the Café Bazar, during the Salzburg Festival – by composer personalities such as Béla Bartók, Arthur Honegger, Maurice Ravel, Paul Hindemith and Anton Webern. The founding committee consisted of Rudolf Réti, Egon Wellesz and the Festival founder and Festival President at the time, Richard Strauss. Further chamber concerts this season bring the best string quartets of our times to Salzburg, including the Hagen Quartet, the Quatuor Ébène and the Jerusalem Quartet. András Schiff joins Isabelle Faust, Daniel Ottensamer, Dénes Várjon, Martin Grubinger and Erwin Falk in performing works by Béla Bartók. Renaud Capuçon teams up with Christoph Koncz, Gérard Caussé, Veronika Hagen, Julia Hagen, Clemens Hagen and Alois Posch to perform Richard Strauss’ Metamorphosen in the version for string septet, among other works. Tobias Moretti and the ensemble wood sounds combine sonnets by William Shakespeare with works by the poet’s compatriot Henry Purcell and other baroque composers.
