Monolithic Undertow alights a crooked path across musical, religious, and subcultural frontiers, exploring a concept that is often described as 'the drone'. Harry Sword traces the line from neolithic Indo-European traditions to the modern underground by way of mid-20th Century New York, navigating a beguiling topography of archeoacoustics, ringing feedback, chest plate sub bass, avant-garde eccentricity, and fervent spiritualism. From ancient beginnings to bawdy medieval troubadours, Sufi mystics to Indian raga masters, North Mississippi bluesmen to cone-shattering South London dub reggae sound systems, Hawkwind's Ladbroke Grove to the outer reaches of Faust, Ash Ra Temple and sonic architects like La Monte Young, Brian Eno, and John Cale. the opium-fueled fug of The Theatre of Eternal Music to the caveman doom of Saint Vitus. the cough syrup reverse hardcore of Swans to the seedy VHS hinterland of Electric Wizard, ritual amp worship of Earth and Sunn O))) and the many touch points in between, Monolithic Undertow probes the power of the drone: something capable of affording womb-like warmth or evoking cavernous dread alike. This story does not start in the twentieth century underground: the monolithic undertow has bewitched us for millennia. The book takes the drone not as codified genre but as an audio carrier vessel deployed for purposes of ritual, personal catharsis, or sensory obliteration, revealing also a naturally occurring auditory phenomenon spanning continents and manifesting in fascinatingly unexpected places. Monolithic Undertow will be a book about music and the very human need for transcendence and intoxication through sound. It seeks to reveal the drone as a tool of personal liberation that exists far outside the brittle confines of commodity culture.
