Then Mick Bolton left the band and after trying several guitarists (Larry Wallis and Bernie Marsden), replaces a very young Michael Schenker would mark the band's sound in the coming years. In 74 released "Phenomenon" and a year later they are joined by Paul Chapman (guitar) leaving the group before the publication of "Force It" (1975). For the recording of their sixth album, "No Heavy Petting" (1976), joins the group Danny Peyronnel (keyboards, guitar) who was replaced by Paul Raymond for recording "Lights Out" (1977). This training would publish "Obsession" (1978) and the magnificent "Strangers in the Night" (1979). Michael Schenker decided to fly solo and left the group and was replaced by Paul Chapman with that record "No Place to Run" (1980). The changes are happening and Paul Raymond left the band and was replaced by John Sloman and later by Neil Carter. In 81 came "The Wild, the Willing and the Innocent" and a year later "Mechanix". In 82 Pete Way left the band and was replaced by Billy Sheehan place with which released "Making Contact" (1983) but sales are not appropriate and decide to separate.
Some time later the band would return to relive a second youth with very good albums like Walk On Water, Covenant and The Visitor among others ...
In this first album of UFO clearly noticed its roots blues mixed with psychedelia and experimentation, the road to the hard rock was still to come. The production is not very good because they counted as few resources but we can appreciate a superb Pete Way on bass. In the recording are two versions, "Who Do You Love" by Willie Dixon and "C'mon Everybody" Eddie Cochran it would be a remarkable success in Japan. Other outstanding issues would "Unidentified Flying Object", "Boogie" or "Follow you Home".
