Korn III: Remember Who You Are is the ninth studio album by the American nu metal band Korn, released on July 13, 2010.  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" is a song by the American nu metal band Korn.  It is the sixth track from the band's self-titled debut studio album.  The song is about how Korn's lead vocalist Jonathan Davis was bullied in high school for being into arts, wearing eyeliner, being into new wave music (for example, Duran Duran), and wearing frilly shirts.  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. Alone I Play is a special limited run DVD/CD combo set by Korn vocalist Jonathan Davis, which was released November 10, 2007 on "Invisible Arts".

"Alone I Play" was recorded and packaged in CD and DVD formats and prepared for sale in no longer than three days, where it is sold at venues where Davis performs (although a commercial release is planned).
