In 1907 Herman Hesse spent a few days mediating and fasting in a cave near Monte Verità. During these days he collected the visions and insights that went on to be very influential in his thinking and shaped some of the most important works of his literary career. The images and sounds of this film were shot there and are a homage to this cave and its possible invocations. Grotta is part of Fieldworks, an ongoing experiment with ambient video and radio frequencies.
