Obsolete (styled °BSΩLE+e on the album cover) is the third studio album by American heavy metal band Fear Factory, released on July 28, 1998. Conceptually, it is a sequel to 1995's Demanufacture. With the success of its fourth single, Cars, a Gary Numan cover that featured Numan himself on vocals, Obsolete would break Fear Factory into the mainstream and remain their highest selling album.
