Le Slieâs â Interaction of Celestial Bodies @ Interfinity Festival
đ«
Fabrizio Di Salvo and Roberto Maqueda present a newly developed instrument based on the physical principles of the legendary Leslie speaker â the rotating loudspeaker system developed in the 1940s for the Hammond organ, which became world-famous for its characteristic, floating, and expansive sound movement. Six metal sound discs, rotating in a circle around the audience, create a vibrating, room-filling sound field â an acoustic experience reminiscent of the movement of celestial bodies and connecting in a unique and innovative way to the exoplanet theme of the Interfinity Festival 2026.
The performance took place in the imposing Maurerhalle at the Basel School of Applied Arts â a unique space whose industrial architecture and raw acoustics made the sound vividly tangible. The circular arrangement of the sound discs, combined with rotating light elements, transforms the space itself into an instrument â an immersive, technically precise sound installation at the intersection of music, machine, and perception.
