Jeff Kolar is a sound artist and curator working in Chicago, USA. His work, described as “speaker-shredding” (Half Letter Press), “wonderfully strange” (John Corbett), and “characteristically curious” (Marc Weidenbaum), includes cross-platform collaboration, low-powered radio, and live performance. His work activates sound in unconventional, temporary, and ephemeral ways using appropriation and remix as a critical practice. His solo and collaborative projects, installations, and public performances often investigate the mundane sonic nuances of everyday electronic devices. Jeff is a free103point9 Transmission Artist, and the founder and acting director of Radius, an experimental radio broadcast platform.
