After a subsequent tour, Iron Maiden started working on their next studio effort, "Seventh Son of a Seventh Son", which featured more progressive rock elements than the band's previous records. Although it became their second release to top the British charts, it was also Dickinson's first album with the band that did not achieve platinum status in the US. Unlike "Somewhere in Time", Dickinson was much more enthusiastic about this album due to its concept and has several song-writing credits. After the following tour in 1988, the band decided to take a year off.
