Sound Proof is a sound art exhibition focusing on the site of the 2012 London Olympic Games. Six artists have been invited to respond to the site in the Lower Lea Valley and to the wider issues and debates surrounding the Olympic project. Using sound materials, drawings and annotations the participating artists have created audio and visual maps that preserve observations of transformation. Taking sound as an audio cartography, Sound Proof forms a unique recording of a neighbourhood that will have completely changed by 2012. The exhibition presents six, 1-hour, sound recordings assembled into a 6-hour programme, with an accompanying set of visual maps contained in this publication.
