Doctor Dark (alternatively stylized as Dr Dark or Dr. Dark) is an upcoming studio album and "modern theater piece/opera" by The Residents. The three-act opera is described as "a journey into the greasy world of euthanasia, drug abuse and an unhealthy obsession with heavy metal", revolving around "a couple of heavy metal kids (Maggot and Mark) and an insomniac Russian physician (Dr. Anastasia Dark)".It was inspired by an unsuccessful 1990 civil action in which heavy metal band Judas Priest were sued by the family of James Vance, a teenager who had attempted suicide by shotgun after listening to the band's music coupled with the life of Armenian-American pathologist and euthanasia activist Jack Kevorkian.
