Le Slie's – Interaktion der Himmelskörper

With Le Slie's, Fabrizio Di Salvo and Roberto Maqueda present a newly developed instrument based on the physical principles of the legendary Leslie loudspeaker - the rotating loudspeaker system that was developed for the Hammond organ in the 1940s and became world-famous for its characteristic, floating, space-filling sound movement. Twelve metal sound disks, which rotate in a circle around the audience, create a vibrating, space-filling sound field - an acoustic experience that is reminiscent of the movement of celestial bodies and ties in with the Interfinity Festival 2026 theme of exoplanets in a very unique and innovative way. Like miniature planets, driven by mechanics, light and sound, they orbit the central performer computer. Each unit unfolds its own "gravitational field" of resonance. Inspired by astrology and cosmology, a sensually tangible, resonant planetary system is created.

The twelve sound stations - partly made of metal, partly of glass - are set in rotation by servo and solenoid motors and precisely controlled by a percussionist. The system is complemented by an adaptive artificial intelligence that reacts in real time and generates independent sound impulses. The interaction between musician and machine creates a dense acoustic network of movement, resonance and rhythmic variation.

The performance will take place in the imposing Maurerhalle at the Gewerbeschule Basel - a unique space whose industrial architecture and raw acoustics make the sound tangible. The circular arrangement of the sound discs, combined with rotating light elements, turns the space itself into an instrument - an immersive, technically precise sound installation at the interface of music, machine and perception.
