Lustmord, the solo project of Welsh artist Brian Williams, is often credited as the creator of the post-industrial genre known as dark ambient. His bleak, disturbing music often utilizes field recordings, deep bass frequencies, and ritualistic instrumentation, such as Tibetan horns. Initially associated with the industrial scene during the early '80s as a member of SPK, he established his signature sound with releases like 1986's Paradise Disowned and 1990's particularly groundbreaking Heresy. Since then, he's collaborated with artists ranging from Robert Rich (on the 1995 classic Stalker) to alternative metal groups like the Melvins (2004's Pigs of the Roman Empire) and Tool (2006's 10,000 Days). He also became a prolific sound design artist for Hollywood films and video games, and his film-scoring output includes 2017's First Reformed. He collaborated with pianist Nicolas Horvath on 2020's The Fall (Dennis Johnson's November Deconstructed).
