Brian Williams is a Welsh industrial musician, sound designer and film score composer. He is often credited for creating the dark ambient genre with albums recorded under the name Lustmord. His experimental work has been described as "not traditionally 'musical'" with "more clearly visual aspects".

Williams was raised in rural Wales, before relocating to London in his late teens. In London, Williams befriended Throbbing Gristle members Cosey Fanni Tutti and Chris Carter, who urged him to make his own music. He started recording as Lustmord in 1980 before joining SPK in 1982. 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, Jarboe, John Balance of Coil, Monte Cazazza, Clock DVA, Chris & Cosey, Paul Haslinger, and experimental sludge group The Melvins on Pigs of the Roman Empire.

Williams released the album Heresy, considered a milestone of the genre of dark ambient, in 1990.

Williams collaborated with Graeme Revell and Paul Haslinger to contribute as "musical sound designer" and occasionally as additional composer to 44 Hollywood film soundtracks, most notably on The Crow and Underworld.

In early 1990s, Williams relocated to California from London with his wife Tracey, who is a fabricator at Legacy Effects. He is an atheist and has noted that while his ominous music gives an impression to some people that he's "somehow dark and [he] live in a castle or in a dungeon", and that he's "very serious about certain aspects of [his] work", he's "not that serious about [himself]".
