On the following albums, 1983's "Piece of Mind" and 1984's "Powerslave", Steve Harris's song-writing monopoly was pushed aside in favour of other members' ideas, with Dickinson contributing to a number of tracks, including the singles "Flight of Icarus" and "2 Minutes to Midnight". Throughout the World Slavery Tour, as part of the new theatrical elements incorporated into the band's stage-show, Dickinson wore a feathered mask during "Powerslave". This was the band's longest tour to date, during which Dickinson considered going home mid-tour, due to the high number of shows. Iron Maiden's management were continually adding dates, until Dickinson demanded that they stop or he would leave the group.
