For its first publication, Edition Kymata has commissioned a five-part long-form work from Stefan Goldmann. This exposé to an incorporeal spatial structure captures infinite reverb responses to five carefully designed immersive spaces. Building on his earlier reverb-only work 'Call and Response' (2022), the capacity of reverberation to enable the experience of impossible architecture is further explored – possibly in its clearest form to date. The five zones of intangible aural sensibility compiled in this box set range from soothing to menacing, inviting to a unique critical listening situation in which the listener's perception is the dynamic side of the exchange while the stimulus persists in profound permanence. The properties of the five enclosures – boundless in the time domain, distinct in their spatial characteristics – reveal themselves completely and can be precisely described in statistical data, allowing for multiple levels of access: a brief visit, long-term contemplation, exclusive ownership. Stefan Goldmann is an electronic music composer based in Berlin, Germany. Edition Kymata is a publishing house for audio arts with a focus on the study of first principles.
