[Testo disponibile solo in inglese] Simone Sims Longo is a sonic and intermedia artist. His sound activity ranges from composition for electronic solo to sound design and sound installations. As a composer he is interested in the creation and manipulation of sound in the digital domain especially focusing on timbre. In his works he often uses a multilevel iteration of samples, investigating asynchronous and polyrhythmic variations of sound textures. Through multichannel speaker diffusion he explores the musical space and exploits the interaction of the sound with architectural elements, fascinated by the natural reverberation and by sound diffusion through different materials. He also focuses his activity on the relation between audio and video in real time, performing acts of visual music that explores the perception of audiovisual phenomena.
