Diabolical Masquerade was the solo-project created by Katatonia''s Anders Blakkheim Nystrm in 1996, to let off more creative steam away from the gothic/doom metal styling of Katatonia. Diabolical Masquerade released 4 albums in total, before Blakkheim laid the project to rest in 2004. Nightwork was the third album by Diabolical Masquerade. It was recorded at The Sanctuary in April 1998. The album was produced by Dan Swan (Opeth, Katatonia) and Blakkheim. Although a solo-project, Blakkheim enlisted the help of Dan Swan to perform the drums, as well as contributing with some keyboards and backing vocals.
