The fear factory band was formed in US, is a heavy metal band with 9 albums, based ob the things i read about them they were quite influencial however i wasnt born when they existed so i cnt really tell but am sure you will know so i decided to listen to their song, "the powershifter" and i loved it. "Fear factory" has a lot in common with obituary in terms of music genre and the fact that they are both from the 90s.
