Unlike Korn's following albums, the album was recorded as a four-piece band and using no Pro Tools or editing.  Vocalist Jonathan Davis stated that the album is "simple" due to the absence of the multi-layered effect present in the band's other albums; Davis added that, the album is "about the vibe."  The album features a return to their roots.  The band hired producer Ross Robinson, who had produced Korn's first two albums, while drummer Ray Luzier was appointed a permanent member of the band (Luzier was formerly a "fill-in" drummer).

Faget (song): "Faget" is a song by the American nu metal band Korn.  It is the sixth track from the band's self-titled debut studio album.

According to Jonathan Davis, he was constantly called names such as "faggot".  Also, there was a rumor that Davis was gay.  Jonathan Davis said he did not know if he was gay or not.  Therefore, Davis tried to get in a relationship with another boy.  However, Jonathan Davis disliked the experience, realizing he is not gay, even if people thought he was.
