Brian "Lustmord" Williams has created a sound that epitomizes the subgenre of dark ambient. He started recording with the seminal industrial ensemble
SPK in the early '80s when that project was at its most caustic. Williams began the Lustmord project as an extension of SPK's more terrifying moments. Lustmord's sound investigations are exquisitely crafted manifestations of horror that balance sublime sound references with the body's natural queasiness about ultra-low frequencies (infrasound -- frequencies below 20 hz -- has been known to cause vomiting, permanent hearing loss, and even death). Lustmord has extracted the eeriness from field recordings made in crypts, caves, and slaughterhouses, and combined it with occasional ritualistic incantations and the haunting wail of Tibetan horns. His seamless treatments of acoustic phenomena encased in digitally expanded bass rumbles have the darkly ambient quality of nightmares that take you to the blackest of abysses.
