Brian "Lustmord" Williams is a musician in the subgenre of dark ambient. He started recording with the industrial ensemble SPK in the early 1980s. He utilizes ultra-low frequencies (infrasound -- frequencies below 20 Hz, which have been known to cause feelings of awe or fear). Lustmord has extracted field recordings made in crypts, caves, and slaughterhouses, and combined it with occasional ritualistic incantations and Tibetan horns. His treatments of acoustic phenomena encased in digitally expanded bass rumbles have a dark ambient quality. Some of Lustmord's most notable collaborations include Robert Rich on the critically acclaimed "Stalker" and experimental sludge group Melvins on "Pigs of the Roman Empire".


Lustmord has been working on Tool's DVD singles and has remixed versions of "Schism" and "Parabola" which were released December 20, 2005. Lustmord also contributed to Tool's 2006 album "10,000 Days".
Recently Lustmord has been collaborating with Maynard James Keenan on his Puscifer project.

The latest Lustmord album [ O T H E R ] is released on July 22 on Hydra Head.
