The video documents the project by Alexandre Burton and Julien Roy, founder of Artificiel Studio, Three Pieces With Titles, commissioned by MUTEK and part of their synesthetic experimentation between sound and image. The ‘three pieces’ of the title refer to the three distinctive movements at the core of the work: the image that controls the sound (photographies activate a software linked to the audio); the sound controls the image (an instrument triggers a camera plus computer system linked to photographs); and the sound is the image is the sound (colour turns into sound, acoustic vibration changes the colour and vice-versa).
