The work starts from a precise cinematographic reference: 2001: A Space Odyssey, not translated in a sculptural image, but in a sound and luminous installation. The initial segment of the famous film by Stanley Kubrick, in which the monkeys discover the upright position - fundamental stage of the evolutionary process - and therefore the struggle for the affirmation, is reproposed in its only acoustic component within an inaccessible perimeter. A column of red light eascapes from this portion of forbidden space. The work was presented for the first time in 2004 on the occasion of Liliana Moro's solo show at the Ambrosetti Foundation in Palazzolo sull'Olio. The artist's interest in the sculptural power of sound is recorded throughout his entire production, since the beginning when he was a student at the Academy of Fine Arts in Brera in 1986 where she presented a series of black boxes with different sound recordings: an alarm clock that scans the time; the cacophonic and bundled noises of a supermarket; a conversation reduced to the soliloquy and the cracked sound of a building site.
