UFO

UFO formed in London in 1969, evolving from a space rock outfit into a hard rock band after German guitarist Michael Schenker joined in 1973. Their mid-1970s albums "Phenomenon" and "Lights Out" featured powerful tracks like "Doctor Doctor" and "Rock Bottom," establishing them as influential figures in British hard rock. Schenker's melodic guitar work during his tenure with the band influenced many subsequent rock and metal guitarists.
