Delving into the histories of electronic music, ventriloquism, archeology and cybernetics, Sarah Angliss explores the tension between our desires and fears when we encounter sound that’s taken flight from its source. Revealing surprising precursors of today’s disembodied electronic sound making, she also considers the esoteric, geological voyages of Daphne Oram. This visionary composer and inventor, who shaped music from intangible electronic waveforms, spent days off seeking resonances under England’s ancient megaliths. Sarah Angliss shares insights from Oram’s personal archives, ahead of the forthcoming reprint of Oram’s book “An Individual Note”.
