Army of Anyone
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
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.
