Interstices-2.0 is the current revision of sound artist Volker Böhm's performance system, consisting of a mix of digital and analogue signals assembled in a modular rack synthesiser. In this set, the artist makes extensive use of feedback signals to explore sound and rhythm in different ways. Playing this instrument is a bit like searching for interstices, those secret niches that only open up after reaching a specific constellation of things and states, where present and past are equally important, and where suddenly a new dimension emerges, stabilises, and takes on its own strong, clear and sharp character.
