Intrigued by the phenomena and history of optical sound, Mariska de Groot makes  comprehensive analog light-to-sound instruments and installations. A new version of her Stirred Mandala performance arises from her ongoing research on optical sound and spiral movements in body and machine and is a result of Mariska’s residency at A4. The spinning pattern of a ‘tone wheel’ is projected on the floor, like a rug of light creating the instrument surface for the performer, while light-to-sound transducers become her playful tools.

This new work was commissioned in 2019 by A4 and Kontejner, as part of the international collaborative project Re-Imagine Europe, co-funded by the Creative Europe Programme of the European Union, and supported using public funding by the Slovak Arts Council and Bratislava Self-Governing Region.
