op7 is a live audiovisual performance that develops a new way of reading the concept of the tunnel as a metaphor of the journey and the survey about the audiovisual perception, through the optical language. The project was realized for the Mixed Media festival taking place at the Hangar Bicocca in front of the installation “Seven Heavenly Doors” of the Belgian artist Anselm Kiefer. Seven entrances, seven tunnels, seven journeys throughout as many experience optical environments looking for the final entire and unique wholeness. ‘Op7' is an ontologically important work, a link between the Italian project tradition and the present research around expressive codes in audiovisual synaesthesy. A cortical centre between accultured electronic music and the modern practices of sampling and digital sound synthesis. A transposition, according to mixed media practices, of the deconstructivist theories of the last century in an interdisciplinary ambit.
