John Bowers works with modular synthesisers, DIY electronics, feedback systems, self-made software, field recordings, esoteric sensor systems, experimental film, and spoken text. He often combines performance with walking and the investigation of selected sites to research an imagined discipline he calls ‘mythogeosonics’. John’s work is primarily improvised and his 2003 monograph Improvising Machines is a commonly cited reference in studies of the improvisation of electronic music.
