*200 copies limited edition* The sound installation 'ÆTER' (2017) by artist and composer Christian Skjødt Hasselstrøm, can be seen as a study of electromagnetism, translating the phenomena into an immersive sonic environment. Consisting of copper antennas and analogue electronic circuitry, the autonomous systems directly capture and transform the ever-present electromagnetic waves in the air around us into low frequency audio material. ÆTER thus “listens” to its surroundings - the nature, technology and the visitor - as well as itself. The piece is therefore constantly changing and invites to expand not only our perception of the world and its dimensions, but also our own perception apparatus. The intention is not to create a performative instrument enabling visitors to play, but rather to create a complex interconnected network. ÆTER takes its inspiration from the Russian scientist and musician Léon Theremin’s (1896-1993) most iconic invention - the theremin - a musical instrument which derived from an attempt to create a surveillance device.
