peripheri.es is a series of ad hoc location based audio broadcasts. These set out to explore the broadcast as the public face of a 'media ecology' that momentarily connects bodies, materials and histories. The project aims to turn the boradcast inside out, to include the many different contexts that intertwine to produce it. Some of these are visible, such as the equipment and materials, while other aspects are more difficult to pin down. How can we expereince that which is usually hidden, radio waves, personal memories, moments from history both lost and documented? Peripheri.es looks to these edges, and draws them back into focus so we can re-think where they belong.
