'This book arises broadly from the research project ‘Exploring the legacy of the 1948 American Australian Scientific Expedition to Arnhem Land’, for which editor Harris was a research associate, and, more specifically, from a 2011 research forum at which the chapters were presented as papers. ‘Circulating’ (in the book title) is not intended literally as being cyclic but rather crossing borders, either among Aboriginal groups, or out of Aboriginal society by means of recordings, or back into Aboriginal society through processes of repatriation, or from a contemporary Western rock genre into one Aboriginal society in a juxtaposition of historical and contemporary experiences and levels of understandings. Similarly, ‘legacy’ (in the project title) is interpreted liberally.' (Introduction)
