An incredibly comprehensive and much-needed addition to the conversation surrounding music technology, this volume is a profound and fascinating reframing of electronic and experimental music history through the lens of composers, performers, practices, concepts, instruments, and communities that have been completely ignored or otherwise severely overlooked in the traditional academic discourse. I highly recommend this for anyone who listens outside of the norm.- Sarah Davachi, musicologist, composer and performer of technology-based music.Histories calcify. This applies to experimental art forms and new technologies as much as it does to more conservative fields. Every so often ideas have to be refreshed, revised, returned to a state of fluidity. This well-curated book is one of those agents of change, dealing as it does with legacies of techno-mysticism, noise as disruption, ethnomusicological field recording, prototypes of net communication, technology as politics and overlooked figures whose significance has only recently been recognised. To apply a Pauline Oliveros maxim to the entire volume, the question is not 'what am I hearing' but 'how am I listening'?- David Toop, musician, author, Emeritus professor, London College of Communication
