The multimedia performance is based on the live interaction of the artist himself with an intermediary installation set up in the form of a scenic space. In video projection, a 3D, interactive, real-time environment characterized by electronic music and visual flows infinitely randomized within a set range of variations, as a form of random composition. The rise and fall "speaks" of + and -, Ying and Yang, of that difference in potential that generates the energy for the engine of every living thing, of individual stories and historical processes, without saying words, instead relying at the meeting between the "pure languages" of audiovision and performativity. The video material was taken live at Casetta rossa (for the FUORINORMA festival, curated by Adriano Aprà) and at the Galleria Galleria d'Arte Moderna di Roma Capitale (for the IL VIDEO RENDE FELICI festival, curated by Valentina Valentini)
