关于瑞士声音实验艺术家Andy Guhl和Norbert Möslang的纪录片。 Drawing on trace elements of Jazz and Arte Povera, Swiss duo Andy Guhl and Norbert Moslang use a range of cracked everyday electronic equipment to create abstract sound environments. Alongside free improvisation, they've devoted over 30 years to obsessively fathoming the potential of generative composition by analogue, non-computer-steered systems for their Voice Crack project. Peter Liechti's "Kick That Habit" is set to be a music film classic - its artful, cinematically unique sequences transcend the usual parameters of documentary. Peter Liechti: 1951 Born in St. Gallen. Studies of Art History at the University of Zurich. Zurich College of Art and Design, diploma in teaching drawing. Since 1986 freelance work in films as scriptwriter, director, producer and cameraman.
