Fear Factory is a Los Angeles, California base metal band. They formed in 1989 and have since released seven full-length albums and a number of singles and remixes. Over the course of their career they have evolved from a succession of styles, as well as steadily pioneered a combination of the styles death metal, groove metal, thrash metal and industrial metal. The resultant sound proved to be enormously influential on the metal scene from the mid-90s and onwards. Fear Factory is also notable among metal bands for their heavy use of science fiction elements in their songs and concept albums. Their most recent album, Transgression, described as a more experimental and atypical effort, has also contained elements of pop music and progressive metal.
