Army of Anyone was a rock supergroup formed by Filter frontman Richard Patrick with two members of rock band Stone Temple Pilots.
 In addition to Patrick on vocals, the band featured brothers Dean DeLeo and Robert DeLeo on guitar and bass respectively, and Ray Luzier, formerly of David Lee Roth's band, on drums.
 The band released one self-titled album in November 2006, which was well-received, but sold well short of the member's multi-platinum selling releases of their other bands.
 After touring in support of the album, the band went into hiatus in mid-2007, with members returning to their respective bands, except Luzier, who joined Korn.
 Despite being relatively inactive since 2007, all members have stayed in contact, and have independently shown interest in working on a second album if the logistics and scheduling of their commitments to other bands ever aligned.
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".
 The album was recorded and videotaped at Malibu's Woodshed Recorder on November 7, 2007, the day before Davis embarked on his first solo tour, the Alone I Play tour.
 "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).
 The album features songs originally composed by Davis and Gibbs for the 2002 film "Queen of the Damned", as well as classic and uncommonly performed Korn songs.
 Despite the fact that this is a solo effort, three members of Korn's backup band appear on "Alone I Play": keyboardist Zac Baird, guitarist Shane Gibson and percussionist Michael Jochum.
 The renowned and eclectic Indian violinist and composer L. Shankar, also known as Shenkar, also makes an appearance.
 The album's title is a pun on Korn's 2002 single "Alone I Break".
Rich versus Roach is a 1959 studio album by drummers Buddy Rich and Max Roach with their respective bands of the time.
 The album is mixed with each of the two bands in a different stereo channel.
Jonathan Davis and the SFA (Simply Fucking Amazings) is the solo band of Korn frontman Jonathan Davis.
Jonathan Howsmon Davis (born January 18, 1971), also known as JD and JDevil (or J Devil), is an American musician best known as the leading vocalist and frontman of the nu metal band Korn.
Bad Manners are an English 2 Tone and ska band led by frontman Buster Bloodvessel.
 Early appearances included "Top of The Pops" and the live film documentary, "Dance Craze".
"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.

 It is one of a number of songs by Bad Manners about 'being fat', (a reference to the round figure of frontman, Buster Bloodvessel).

 Its signature melodic lines were a simple but careful blend of brass instruments and lead harmonica theme, played by Alan Sayag (Winston Bazoomies).
