His interest in chaotic and polymetric rhythms, unconventional tunings and the psychoacoustic properties of sound and field recording manifest in site-specific sound installations based on resonant properties of spaces and materials. He has given workshops on sonification, field recording, electromagnetic listening and programming for artists and created the Elektrosluch – electromagnetic listening device. In 2009, he started the label LOM, focussed on East/Central European experimental art and music, opening the LOM space for contemporary sound in Bratislava nine years later.WebsiteCommissioned by INA GRM as part of Re-Imagine Europe, co-funded by the Creative Europe programme of the European Union.
