In 2012, Thomas Gardner and Salome Voegelin hosted a colloquium, entitled "Music - Sound Art: Historical Continuum and Mimetic Fissures", at the London College of Communication, University of the Arts London. This colloquium dealt with the current fervent debate concerning the relationship between sound art and music. This book proposes the opening of the colloquium to a wider readership through the publication of a decisive range of the material that defined the event.
