Lustmord (b. Brian Williams), is a Los Angeles, CA, USA dark ambient / industrial electronica musician, who started recording with SPK (early-1980s). He utilizes ultra-low frequencies - infrasound (i.e. below 20Hz, known to cause feelings of awe or fear). Lustmord has extracted field recordings (made in crypts, caves & slaughterhouses), occasionally combined these with ritual incantations, Tibetan horns & other acoustic phenomena treatments - often encased in expanded bass rumbles.
