UFO were an English rock band formed in London in 1968. They became a transitional group between early hard rock and heavy metal and the new wave of British heavy metal. The band's final lineup consisted of vocalist Phil Mogg, lead guitarist Vinnie Moore, rhythm guitarist and keyboardist Neil Carter, bass guitarist Rob De Luca, and drummer Andy Parker. They had gone through several line-up changes, leaving Mogg as the only constant member, and had disbanded three times. The band's classic line-up comprised Mogg, Parker, bassist Pete Way, keyboardist Paul Raymond and former Scorpions guitarist Michael Schenker. In May 2018, Mogg announced that he would retire from UFO after one last tour as a member of the band in 2019; however, their farewell tour was set to conclude in 2022 before it was cancelled, due to Mogg's health issues. Mogg confirmed UFO's third disbandment in April 2024.
Over a career spanning five decades, UFO had released 23 studio albums, 14 live albums and 16 compilation albums. They achieved moderate success in the late 1970s and early 1980s with several albums and singles in the UK and US Top 40 charts, and have sold over 20 million records worldwide.
