Casimir Geelhoed is a 21-year-old Amsterdam based composer, producer and creative coder. After education at the Royal Conservatory in The Hague and Utrecht School of Arts, he came to surface with his dark experimental post-club project HOEK, releasing two EP's on Fog Mountain and playing at renowned festivals such as Rewire, Incubate and Le Guess Who?. Geelhoed uses both his musical and technical abilities to create powerful and meaningful music, valuing heartfelt emotions over technical perfection.
For 4DSOUND’s exhibition of evolving sound sculptures Ecologies of Listening presented at the Spatial Sound Institute in Budapest, Geelhoed created a personal performance based on the associative qualities of spatial sound and movement in space. The performance has mostly been developed during night time being alone in the 4dsound studio, trying to recall and recreate memories and feelings on both a conscious and subconscious level.
In 2015 Geelhoed joined 4DSOUND's development team as a junior developer before becoming part of technical staff of the Spatial Sound Institute from 2016. Being part of the development team of 4DSOUND, he has been developing his own tools to generate meaningful and evocative movements of elements in space. Specifically for this performance he wrote software to control the behaviour of sound sources in the space, mimicking the working of an ecosystem.
