Perverse is the third studio album by British rock band Jesus Jones, released in 1993 on Food Records.
 After their international success following the release of "Doubt" (1991), Jesus Jones, especially band leader Mike Edwards, conceived "Perverse" as a darker, more contemporary album.
 Fusing rave and techno music into more traditional rock and pop song structures, the album is heavier than its predecessors and features lyrics that concern the future.
 Edwards wrote the lyrics of the album during the band's 1991 tour, using a Roland W-30 sampler to conceive songs in their earliest stages.
Never Enough: The Best of Jesus Jones is a compilation album/greatest hits album by British alternative rock/dance band Jesus Jones, released by the band's former record label EMI on 27 May 2002.
Culture Vulture !
 is an EP by the British rock band Jesus Jones.
 Though considered by some to be an album due only to its length, it is an EP, since only the first four tracks are meant to be heard as fully produced songs.
 The remaining seven tracks are the "stems" of the title track, meaning that each one is the composite of all the singular recordings that are combined to make up every individual instrumental or vocal performance used in the song; these were added in order to give listeners the opportunity to remix the song themselves, and were not intended for casual listening.
 Fans were also encouraged to submit their remixes to the band, who then selected 24 of them which were hosted on the official Jesus Jones site for a period of time.
"Right Here, Right Now" is a song by British alternative dance band Jesus Jones from the album, "Doubt".
 It was released as the album's second single in September 1990 (approximately four months before the release of "Doubt").
 Despite spending only 9 non-consecutive weeks on the UK Singles Chart and peaking at number 31, it became a top ten hit in the United States; it topped the "Billboard" Modern Rock Tracks chart and reached number 2 on the "Billboard" Hot 100 in July 1991, only behind "Everything I Do (I Do It For You)" by Bryan Adams.
The 77s (alternatively spelled The Seventy Sevens or The 77's) are an American rock band consisting of Michael Roe on vocals/guitar, Mark Harmon on bass and Bruce Spencer on drums.
"International Bright Young Thing" is a song by the British alternative dance band Jesus Jones.
 It was released as the third single from their second album "Doubt", and was a top-ten hit in Britain.
 It followed "Real Real Real" and "Right Here, Right Now".
 All three singles were included on a Jesus Jones compilation album "" released in 2002.
London is the fifth album by the British rock band Jesus Jones in 2001 through Koch Records.
 Following the commercial failure of 1997's "Already" which led to the band and EMI parting ways, the band took a hiatus before regathering for the recording of "London" for Koch/Mi5 Recordings, with a more alternative rock approach as opposed to the techno sounds on their previous albums.
 The album had low-key promotion, initially only being released in the United States.
 Two EP's were released from the album, "Nowhere Slow" and "In the Face Of All This".
Jesus Jones are a British alternative rock band from Bradford-on-Avon in Wiltshire, formed in late 1988, recorded and performed in the late 1980s into the 2000s.
