Roberto Maqueda & Fabrizio di Salvo ~ Le Slie's

Polyphonic Fields by Abhishek Mathur

«Friction brings movement and this friction makes me move personally.» Fabrizio di Salvo & Roberto Maqueda

Artist Bio

Sound artists Fabrizio Di Salvo (born 1981) and Roberto Maqueda (born 1991) present Le Slie's, a kinetic sound installation centered on the eponymous percussion instrument developed by Di Salvo. The creation is based on the specific use of the Doppler effect via Leslie speakers. This mass-produced electromechanical speaker system generates a characteristic vibrato and tremolo through the Doppler effect and periodic level fluctuations. For Le Slie's, it has been further developed into an independent acoustic instrument.

This podcast series presents conversations and sounds from the 2025 edition of the Klang Moor Schopfe Festival. Each episode features one particular work and is an attempt to capture the underlying philosophies and processes of the artists in their own words, set to recordings of the installations and occasional sonic interventions by the author.

The next edition of the Klang Moor Schopfe festival will take place from Sept 2 - 12, 2027.

Polyphonic Fields by Abhishek Mathur

«We try to create a kind of living creature that creates its own music.» Peter Bosch & Simone Simons

Artist Bio

The Valencia-based artist duo Peter Bosch (born 1958) and Simone Simons (born 1961) have been developing autonomous dynamic music machines since the 1990s. The work they are showing at the Museum Gais is a new piece in their series Último Esfuerzo Rural (Last Rural Effort), which they began in 2017. This series consists of room-filling kinetic sound installations for which they use everyday objects found on site—in the case of Gais: metal vessels ranging from milk pails to watering cans. They arrange these found objects into whimsical ensembles, set them in motion, and thus create a surprising sound collage. With this work, they continue their series of pieces in which they translate the properties and history of objects characteristic of a region into a sculptural soundscape.
