The X Factor is the tenth studio album by Iron Maiden, released on 2 October 1995. It is the first of two albums by the band to include Blaze Bayley, formerly of Wolfsbane, as vocalist, replacing Bruce Dickinson, who left the band following their previous tour to pursue a solo career. The album takes a darker tone than the band's first nine releases, due to the lyrics being based on personal issues surrounding Steve Harris at the time, who was in the midst of a divorce. This is reflected in the cover artwork, which graphically depicts the band's mascot, Eddie, being vivisected by machine.
