Born in the former Czechoslovakia, experimental composer Jonáš Gruska studied at the Institute of Sonology in The Hague and Academy of Music in Kraków. 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.
