Phenomenon is the third studio album by English hard rock band UFO, released in May 1974. It was the band's first album to feature lead guitarist Michael Schenker, who replaced Mick Bolton.
Production
Their third studio album, Phenomenon was UFO's debut with major label Chrysalis Records and their first to be released in the United States. With the arrival of ex-Scorpions lead guitarist Michael Schenker, Phenomenon saw UFO begin to leave their blues-based "space rock" sound behind and transition to a more straightforward hard rock sound.
The album was produced by Leo Lyons, bassist of British rock group Ten Years After. All tracks were recorded at Morgan Studios in London. The original cover design and photos were by Hipgnosis.
Influence
British heavy metal band Iron Maiden released a cover version of "Doctor Doctor" as the b-side of the "Lord of the Flies" single in 1995. They also included it in their Eddie's Archive boxed set collection of 2002.
