When the English experimental band Throbbing Gristle was formed, its main intention was not to create songs that people would want to listen to repeated times; rather, it was to explore the darker and more obsessive sides of the human mind. This is appropriate, considering the band's characteristic sound centers heavily around prerecorded tape loop experimentation and eerie soundscapes that border on the morbid, set against projections of pornography and Nazi concentration camps. Formed in 1975 by members of a performance art group, Throbbing Gristle would gain a fairly big reputation for its avant-garde sensibilities, before breaking up in 1981.
