John Kenneth Wetton (12 June 1949 – 31 January 2017) was an English singer, bassist, and songwriter.
 He was born in Willington, Derbyshire, and grew up in Bournemouth, Dorset.
 He rose to fame with bands Mogul Thrash, Family, King Crimson, Roxy Music/Bryan Ferry, Uriah Heep, and Wishbone Ash.
After completing their second US tour in mid 1971, John Weider left the band and was replaced by John Wetton on bass and vocals .
 The band's direction was notably changed with Wetton bringing along his trademark propulsive performance style, as evidenced on the album opener "Between Blue and Me".
 After only a year and one more album, Wetton left to join the latest line-up of King Crimson and was replaced by Jim Cregan.
 "Fearless" was the first Family album to chart in the United States, reaching #177 on the Billboard 200 in March 1972, and staying on the charts for 7 weeks.
Gravitas is the fourteenth studio album by British progressive rock band Asia, released on 25 March 2014.
 Written and produced by John Wetton and Geoff Downes, it is the group's first release to feature their new guitarist, Sam Coulson, who replaced Steve Howe in January 2013 after the latter retired from the band, and their final studio album before Wetton died of cancer in 2017.
 "Gravitas" was originally announced under the name "Valkyrie" which would eventually come to be the name of the lead single.
Ultimate Zero Tour - Live is a live album by Eddie Jobson and his U-Z Project.
 The album is compiled from 2009 performances in Poland, Russia, and the United States by various line-ups.
 Musicians include John Wetton, Tony Levin, Greg Howe, Trey Gunn, Marco Minnemann and Simon Phillips.
 The album marks the first time Jobson and Wetton publicly collaborated since the breakup of UK in 1979.
Icon is a studio album recorded and released by Asia band members John Wetton and Geoffrey Downes in 2005.
 It is the first in the "Icon" franchise (though they previously recorded in 2002 the album "Wetton Downes", a precursor to the Icon series).
Jack-Knife's I Wish You Would was a 1979 one-off recording project of John Wetton (lead vocals, bass, keyboards), Richard Palmer-James (guitars), John Hutcheson (Hammond organ, piano, backing vocals), and Curt Cress (drums and percussion).
 Palmer-James had previously written lyrics for the band King Crimson, of which Wetton was a member.
Wetton/Downes (sometimes stylised as Wetton-Downes or Wetton & Downes, though the album is given no official title) is the first album released by former (at the time) Asia bandmates John Wetton and Geoff Downes, and is a precursor to their "Icon" franchise.
 It is essentially a collection of (previously unreleased) demo tracks, mostly recorded during Asia's hiatus in the late 1980s through the time of their brief reformation in 1990.
 In September 2017, Downes announced (via his Twitter account) the re-release of this title, with remastered sound and additional tracks, as "Icon Zero"
Qango were a short-lived progressive rock band, a spin-off from Asia.
 In 1999, an attempt was made at a partial reunion of the progressive rock supergroup Asia involving John Wetton (bass, vocals), Carl Palmer (drums) and Geoff Downes (keys), with David Kilminster to be on guitar.
 However, Downes withdrew from plans, choosing to stick with John Payne in their Asia line-up.
 Wetton and Palmer instead formed Qango with Kilminster and John Young on keys (who had briefly replaced Downes in Asia in 1989).
 The band's live set was based on songs by Asia and Palmer's former band Emerson, Lake & Palmer.
Gackt Camui (神威 楽斗 , Kamui Gakuto , born July 4, 1973) , better known by his stage name Gackt, is a Japanese musician, singer, songwriter and actor.
 He has been active since 1993, first as the frontman of the short-lived independent band Cains:Feel, and then for the now defunct visual kei rock band Malice Mizer, before starting his solo career in 1999.
 He has released nine studio albums and, with forty-eight singles released, holds the male soloist record for most top ten consecutive singles in Japanese music history.
 His single "Returner (Yami no Shūen)", released on June 20, 2007, was his first single to reach the number one spot on the Oricon charts.
U.K. were a British progressive rock supergroup originally active from 1977 until 1980.
 The band was composed of singer/bassist John Wetton (formerly of King Crimson, Roxy Music, Bryan Ferry's band and Uriah Heep), keyboardist/electric violinist Eddie Jobson (formerly of Curved Air, Roxy Music and Frank Zappa's band), guitarist Allan Holdsworth (formerly of Tempest, Soft Machine, The New Tony Williams Lifetime and Gong) and drummer Bill Bruford (formerly a full member of Yes and King Crimson, and also a tour drummer for Genesis), who was later replaced by drummer Terry Bozzio (formerly of Frank Zappa's band).
 UK reformed with John Wetton, Eddie Jobson and Terry Bozzio for a world tour in 2012.
