UFO are an English rock band that was formed in London in 1969.
 They became a transitional group between early hard rock and heavy metal and the new wave of British heavy metal.
 The band's current lineup includes vocalist Phil Mogg, guitarist Vinnie Moore, bass guitarist Rob De Luca, keyboardist and rhythm guitarist Paul Raymond and drummer Andy Parker.
 They have gone through several line-up changes, leaving Mogg as the only constant member, and had two hiatuses (1983–1984 and again from 1989 to 1991).
 The band are also notable for featuring former Scorpions guitarist and MSG founder Michael Schenker, who was a member of UFO from 1973 to 1978 and again, occasionally, between 1993 and 2003, when Moore replaced him.
Legends of Rock: Live at Castle Donington is a DVD released by German guitarist Uli Jon Roth.
 It features Roth's headlining show at Castle Donington, Leicestershire, England in 2001, along with his special guests Michael Schenker, Phil Mogg, and Pete Way from UFO, and Jack Bruce from Cream.
 Released in 2002.
Phillip John Mogg (born 15 April 1948, Wood Green, North London) is the lead singer for the English rock band UFO, which he formed with longtime friends Pete Way and Andy Parker.
 Mogg wrote the majority of the band's lyrics, with the music being written by Way, Michael Schenker, and later, Paul Raymond, but Schenker left to launch his solo career in 1979.
 Beginning in 1997, Mogg and Way, under the moniker Mogg/Way, released a couple of albums- "Edge of the World" and "Chocolate Box".
 With UFO on hiatus, Phil formed another side project, $ign of 4.
 In late 2003, having regained the rights to the UFO name from Schenker, Mogg spoke with Pete Way and Paul Raymond, and ended up having a reunion tour which later brought the band back for good, with newly hired American guitarist Vinnie Moore.
 The band then released several new albums : "Showtime", "You Are Here", "The Monkey Puzzle", "The Visitor", "Seven Deadly" and "A Conspiracy of Stars".
The Equatorial Stars is the third studio ambient album by British musicians Robert Fripp and Brian Eno.
 The album was released in 2004, which marked almost 30 years since the two musicians had collaborated on their second album, "Evening Star", in 1975.
Misdemeanor is the twelfth studio album by the British hard rock band UFO.
 After the disastrous tour supporting "Making Contact", UFO disbanded, with Phil Mogg spending time in Los Angeles, where he contacted (through Mike Varney) guitarist Atomik Tommy M.
 Mogg decided to start a new band, involving the new American guitarist and Paul Gray, who had played bass guitar in the last UFO tour.
 The three of them recruited former UFO keyboard player Paul Raymond and drummer Robbie France and started writing new material.
 Chrysalis Records signed the new band as UFO and assigned experienced producer Nick Tauber for the recording process of a new album.
 France resigned before the recording started and was replaced by former Magnum drummer Jim Simpson.
 Paul Raymond quit the band during their US tour in August 1986 and was replaced for the rest of the tour by David Jacobson.

 As a singer Nince Henry has also released some songs which have won air play on Ugandas Radio stations, songs like Cinderella, Mali yangu, mpola mpola and others.
 In 2012, Nince had some song writing projects with juliana, following the writing of the song "Sikyakaaba" which juliana was supposed to release-however there were some unknown disagreements between the two parties (Nince and juliana) and the two musicians produced the same song with the same title and lyrics, this caused confusion over who owned the song, which aroused mistrust between the two musicians.
 In 2013 Nince stage his first concert "MPOLA MPOLA CONCERT"

The Plot was a heavy rock band formed in 2003 by bassist Pete Way and his long-time friend, guitarist Michael Schenker.
 The two wanted to form a band like UFO again and asked Phil Mogg and Andy Parker to regroup with them, but tension was still fiery between the ex-bandmates, although Way, Schenker and Mogg had been involved in recording as UFO for the album "Sharks" in 2002.
 So instead, Way and Schenker recruited drummer Jeff Martin.
 This band released one album, also entitled "The Plot".
