Synopsis
Brothers Bernard and François Baschet (born in 1917 and 1920, respectively) have been two of the pre-eminent pioneers in building experimental musical instruments and creating sound sculptures. After working together in a symbiotic relationship for decades, they parted ways professionally in the mid-1970s to pursue their own individual artistic aspirations. The film follows several years in the lives of the two brothers, documenting the musical and artistic marks they have left throughout the world.
