Tracing the the potential of sound infrasound and ultrasound to access anomalous zones of transmission between the realms of the living and the dead For as long as recording and communications technologies have existed operators have evoked the potential of sound infrasound and ultrasound to access anomalous zones of transmission between the realms of the living and the dead In Unsound Undead contributors from a variety of disciplines chart these undead zones mapping out a nonlinear timeline populated by sonic events stretching from the 8th century BC the song of the Sirens to 2013 acoustic levitation with a speculative extension into 2057 the emergence of holographic and holosonic phenomena For the past seven years the AUDINT group has been researching peripheral sonic perception unsound and the ways in which frequencies are utilized to modulate our understanding of presence non presence entertainment torture and ultimately life death Concurrently themes of hauntology have inflected the musical zeitgeist resonating with the notion of a general cultural malaise and a reinvestment in traces of lost futures inhabiting the present This undead culture has already spawned a Lazarus economy in which Tupac ODB and Eazy E are digitally revivified as laser lit holograms The obscure otherworldly dimensions of sound have also been explored in the sonic fictions produced by the likes of Drexciya Sun Ra and Underground Resistance where hauntology is virtually extended the future appears in the cracks of the present The contributions to this volume reveal how the sonic nurtures new dimensions in which the real and the imagined fictional hyperstitional speculative bleed into one another where actual sonic events collide with spatiotemporal anomalies and time travelling entities and where the unsound serves to summon the undead ContributorsLawrence Abu Hamdan Lendl Barcelos Charlie Blake Lisa Blanning Brooker Buckingham Al Cameron Erik Davis Kodwo Eshun Matthew Fuller Kristen Gallerneaux Lee Gamble Agnes Gayraud Steve Goodman Anna Greenspan Olga Gurionova S Ayesha Hameed Tim Hecker Julian Henriques Toby Heys Eleni Ikoniadou Amy Ireland Nicola Masciandaro Ramona Naddaff Anthony Nine The Occulture Luciana Parisi Alina Popa Paul Purgas Georgina Rochefort Steven Shaviro Jonathan Sterne Jenna Sutela Eugene Thacker Dave Tompkins Shelley Trower and Souzana Zamfe
