Thomas Gardner is a sound artist and musician,  interested in the links between music, field recording and speech. These are explored in the context of post war art-music and the increasingly political understanding of sound art, and lead to the making of work which attempts to mediate the legacy of trauma and search for new forms of representation. The research context for this is the developing field of ‘Audio Testimony’, which links educational work  addressing the legacies of conflict with the diverse understandings of audible testimony found in sound art.
