Invariably the origin of cyberpunk music lies in the synthesizer-heavy scores of cyberpunk films such as "Escape from New York" (1981) and "Blade Runner" (1982). Some musicians and acts have been classified as cyberpunk due to their aesthetic style and musical content. Often dealing with dystopian visions of the future or biomechanical themes, some fit more squarely in the category than others. Bands whose music has been classified as cyberpunk include Psydoll, Front Line Assembly, Clock DVA, Angelspit and Sigue Sigue Sputnik.
