and notes the origins of industrial
Early influences
Luigi Russolo's 1913 work The Art of Noises is often cited as the first example of the industrial philosophy in modern music. After Russolo's musica futurista came Pierre Schaeffer and musique concrète, and this gave rise to early industrial music, which was made by manipulating cut sections of recording tape, and adding very early sound output from analog electronics devices.
Also important in the development of the genre was the Dada art movement, and later the Fluxus art movement.
Edgard Varèse was also a major pioneer in electronic music. His composition Poème électronique, for example, debuted at the 1958 Brussels World's Fair in the Philips Pavilion.
Lou Reed's 1975 record Metal Machine Music is widely considered in the industrial community the first actualized and sucessful Industrial album.
