Skillet is an American Christian rock band formed in Memphis, Tennessee in 1996.
 The band currently consists of husband John (lead vocals, bass) and wife Korey Cooper (rhythm guitar, keyboards, backing vocals) along with Jen Ledger (drums, vocals) and Seth Morrison (lead guitar).
 The band has released nine albums, two receiving Grammy nominations: "Collide" and "Comatose".
 Two of their albums, "Awake" and "Comatose", are certified Platinum by RIAA while "Rise", is certified Gold as of 12, 2016 .
Jason Andrew Pierce (born 19 November 1965 in Rugby) is an English musician.
 Currently the frontman and sole permanent member of the band Spiritualized, he previously co-fronted alternative rock band Spacemen 3 with Peter Kember.
 He has worked under the name J. Spaceman.
Congratulations is the second studio album by American rock band MGMT, first self-released through MGMT's website on March 20, 2010 with a general release following on April 13, 2010 by Columbia Records.
 The album marks a departure from the synthpop style that first brought the band acclaim on their debut studio album "Oracular Spectacular" and features a more psychedelic, progressive and guitar-driven sound.
 MGMT began writing the tracks that would ultimately appear on "Congratulations" in early 2009.
 They eventually headed to a Malibu studio to work on the album, with producer Peter Kember (Sonic Boom), an ex-member of Spacemen 3, where vocal contributions from Royal Trux singer Jennifer Herrema were also recorded for the album.
 VanWyngarden has stated that the album is influenced by the band's massive rise in popularity since "Oracular Spectacular'"s release.
 "It's us trying to deal with all the craziness that's been going on since our last album took off.
 Sometimes it just doesn't feel natural".
Alien Youth is the fifth album released by the Christian rock band Skillet.
 Developing their sound into hard-hitting industrial rock, it was released August 28, 2001 through Ardent Records.
 This was the first Skillet album to include guitarist Ben Kasica, replacing Kevin Haaland.
 Kasica joined Skillet late in the recording process for the album, only recording guitars on "Earth Invasion".
 It peaked at No. 141 on the "Billboard" 200 and No. 16 on The Australian Christian Albums Chart.
Recurring was the fourth and final Spacemen 3 studio album, finally released (after considerable delay) in February 1991, some time after the band had broken up.
 By the time the album was recorded, relations between the band had soured to the extent that the record is in 2 parts - the first side by Peter Kember, and the second by Jason Pierce.
Spacemen 3 were an English alternative rock band, formed in 1982 in Rugby, Warwickshire by Peter Kember and Jason Pierce.
 Their music was "colourfully mind-altering, but not in the sense of the acid rock of the 1960s; instead, the band developed its own minimalistic psychedelia" (Stephen Erlewine, "AllMusic").
 Spacemen 3 had their first independent chart hits in 1987, gaining a cult following, and going on top have greater success towards the end of the decade.
 However, they disbanded shortly afterwards, releasing their final studio album post-split in 1991 after an acrimonious parting of ways.
 They gained a reputation as a 'drug band' due to the members' drug taking habits and the candid interviews and outspoken views of Kember about recreational drug use.
 Kember and Pierce were the only members common to all line-ups of the band.
 Both founding members have enjoyed considerable success with their respective subsequent projects: Sonic Boom/Spectrum and Spiritualized.
Ardent Worship is the fourth album by the Christian rock band Skillet.
 It was released in 2000 by Ardent Records seven months after "Invincible".
 It is a worship album consisting of both live and studio recordings of six songs written by Skillet and four songs covering other artists.
 Original Skillet members Ken Steorts and Trey McClurkin appear on "Safe With You" and "Shout To The Lord" to finish the live set with fellow founding member John Cooper.
 This is the only Skillet album with no music videos and the first album with Lori Peters on drums, who replaced Trey McClurkin.
 Two songs come from previous Skillet albums, "Safe With You" being from their self-titled album and "Angels Fall Down" being the hidden track on "Invincible".
Peter Kember (born 19 November 1965) is an English musician and producer, more usually known as Sonic Boom, and was a founding member of alternative rock band Spacemen 3.
Experimental Audio Research (commonly shortened to E.A.R. or EAR) is a loose collective of experimental musicians formed around Peter Kember (a.k.a. Sonic Boom), formerly of Spacemen 3.
 While Spacemen 3 were a relatively traditional rock and roll band with strong experimental leanings, E.A.R. is essentially a free improvisation project, creating instrumental music characterized by lengthy, droning textures and slowly evolving structures.
Skillet is the self-titled debut release from the Christian rock band Skillet.
 Released in 1996 as an enhanced CD and audio cassette from ForeFront Records and Ardent Records, it showcases Christian lyrics with a grunge rock sound.
 Skillet was, at the time, a three-piece band composed of John Cooper on vocals, bass and piano, Trey McClurkin on drums and back-up vocals and Ken Steorts on guitar, back-up vocals and the guitar synth.
