UFO

UFO, an English hard rock institution, helped pave the way for the New Wave of British Heavy Metal, with seminal acts like Iron Maiden, Judas Priest, and Def Leppard citing the band as a significant influence. Led by vocalist Phil Mogg, who has been the group's sole constant member since its formation in 1968, UFO enjoyed commercial success in the '70s and '80s with hits like "Rock Bottom," "Lights Out," and "Doctor, Doctor." Their 1979 concert album Strangers in the Night is often cited as one of the greatest live rock albums. UFO underwent numerous lineup changes over the years -- guitarist Michael Schenker, formerly of Scorpions, joined the band in 1973 and contributed significantly to their sound before leaving in 1978 -- but managed to release 22 studio albums, 14 live recordings, and numerous compilations before ceasing operations in 2024.
