As part of Maerie C. Fricke’s solo exhibition at Karlskirche Kassel, Samuel Julian Grace was invited to response to the show. 

Samuel worked with the church organ, a deeply institutionalised instrument, using its live sound alone as input for Pure Data, an open-source audio software. The processed sound was then layered back onto the organ in real time, creating a shifting sonic field. 

By combining the historical authority of the organ with open-source digital tools, feedback loops and irregular delay lines,  the work destabilised the listener’s perception of the instrument. The performance moved fluidly between acoustic and digital sound, making it deliberately difficult to distinguish what originated from the physical organ and what was electronically transformed. 

The piece was performed live with Isa Glöckner, the church’s organist.
