Lustmord is definitely the most important and recognized music venture of a Scottish musician, sound engineer and film score composer Brian Williams. Started in 1980, Lustmord is often considered the first dark ambient project in history, and the album Heresy from 1990 was hailed as the milestone of the whole genre.

For Brian Williams, basically every sound material serves as means of creating his atmospheric, dark music. In his works he uses field recordings from crypts, catacombs, caves, slaughterhouses, shelters, mines, cathedrals, as well as signals from the outer space, which he skillfully combines with ritualistic incantations and Tibetan horns. He treats all available (although carefully selected) acoustic phenomena by enriching them with digital bass effects, this way creating the best quality dark ambient.

Lustmord has collaborated with, among others, Tool, The Melvins, Chris & Cosey (Throbbing Gristle), SPK, John Balance (Coil), Paul Haslinger (Tangerine Dream), Robert Rich, Clock DVA, Current 93 and Nurse with Wound. He is also a member of the group Puscifier, started by Maynard James Keenan, a vocalist of Tool and A Perfect Circle. He has provided remixes for Tool, Jarboe (Swans), Venetian Snares, Lori Carson, Mortiisa, Isis, Puscifer and Nadja. He has contributed to 44 Hollywood film soundtracks, and his sound effects have been featured in numerous video games.
