Industrial music
In his book "Interrogation Machine: Laibach and NSK", Alexei Monroe argues that Kraftwerk were particularly significant in the development of industrial music, as the "first successful artists to incorporate representations of industrial sounds into nonacademic electronic music." Industrial music was created originally by using mechanical and electric machinery, and later advanced synthesizers, samplers and electronic percussion as the technology developed. Monroe also argues for Suicide as an influential contemporary of the industrial musicians. Groups cited as inspirational by the founders of industrial music include The Velvet Underground, Joy Division, and Martin Denny. Genesis P-Orridge of Throbbing Gristle had a cassette library including recordings by the Master Musicians of Jajouka, Kraftwerk, Charles Manson, and William S. Burroughs. P-Orridge also credited 1960s rock such as The Doors, Pearls Before Swine, The Fugs, Captain Beefheart, and Frank Zappa in a 1979 interview.
