This unique production of Carl Maria von Weber’s ‘Der Freischütz’ was created to celebrate both the piece’s 200th premiere anniversary at Konzerthaus Berlin and the 200th anniversary of the famed concert hall itself. For this production, Catalan theatre group La Fura dels Baus – internationally acclaimed for its avant-garde opera – created a virtual forest in the Konzerthaus’ Great Hall.
