In Rumour and Radiation, Paul Hegarty provides novel insight into and strong evidence of the audiovisual nature of video arts as it turns out to play a key role in contemporary crossmedia practices. His arguments are convincing: that sound and image in video are different yet connected to each other. His many examples are fascinating, particularly the importance of sounds in the creation of spatial effects in video works where the artists, like Bruce Nauman, Jane and Louise Wilson, Christian Marclay, or Ryoji Ikeda, explore materials and perceptions across usual borders. This work is an illuminating source that sets a new tone for readjustments and critical engagement with multi-sensorial processes in our still predominantly 'visually' conceived culture.
