Documentary about European artist Peter Vogel and his work, 'The Sound of Shadows'. The film captures Vogel at a Paris exhibition and at his Freiburg studio as he discusses the piece which creates sound based on the observer's movement. Experts such as curator and writer David Toop also discuss Vogel's work.

"Works with Sound" presents a complex body of work, comprising thirty years of sculptures, drawings, environments, and performances. Fox, who since the 1960s radically rejected traditional art forms and sought new ways of artistic expression, has been increasingly concerned with investigating the seldom-observed energetic aspects of materials. Hence, sound gained a central significance in his works. The artist is dedicated to finding sounds that make energies palpable and connect the listener and his physical surroundings.
