Heinz Holliger is one of the "most influential creators and visionaries of our time" (Laudatio for the Swiss Grand Prix Music 2015). Like no other, he stands for the international Swiss music scene. And since his beginnings as a solo oboist, he has been a recurring guest at the "Engadin Concert Weeks," as the Engadin Festival was then called. In this anniversary year, he returns for the tribute concert in honor of the festival and the people who have shaped it over the years. The founders Ernst Schulthess, pastor of Silvaplana, and his brother Walter Schulthess, concert agent and composer, accomplished the feat of bringing world-class artists to the Engadin. Shortly before, Walter Schulthess had already co-founded the Lucerne Music Festival and, as a music agent, had excellent contacts in the music world. Clara Haskil, Dinu Lipatti, Edwin Fischer, Pierre Fournier and many others performed in the Engadine and also attracted prominent guests such as Hermann Hesse. Before the concert, Claudio Chiogna, former director of the festival, talks to musicologist Dominik Sackmann about the history of the festival.
