Nightmare in London is a 1965 heavy metal/Gothic rock album by Christopher Lee, considered to be one of the most influential albums of all time. His third studio album, it was produced by Lee in three weeks, during which he was under the heavy influence of morphine and alcohol, to better reflect the "mood" of mid-1960's Reconstruction England.
Regarded as a cultural milestone, the eight-song album was initially banned in England but was a major seller in the United States, where it became the cornerstone of the emerging hard rock culture. The album's success helped raise Lee's profile in the United States, initially at the underground rock level but later in American culture as well, and Lee's bizarre and spectacular performances during his 1968 "Nightmare in America" tour was said to have inspired dozens of future rock artists in the diversifying musical scene emerging in the late 1960's and early 1970's, and rejuvenated interest in Gothic themes in film and television, including the 1970's Van Helsing trilogy, the Gothic America television series (1972-1974), and the counterculture movement of the mid-to-late 1970's.
Nightmare in London is sometimes referred to as the first heavy metal album, the first Gothic rock album, and even the first punk album, as many punk artists in the late 1970's trace their inspiration back to Lee's work in the 1960's. Other musical historians categorize Nighmare in London as a forerunner of protest music, due to many of the mature themes in its songs. Of Lee's five official albums, it is by far the most popular and Lee regards it as his finest and most genuine work.
