Context paragraphs:
Killers (Iron Maiden album): Killers is the second studio album by the English heavy metal band Iron Maiden, released on 2 February 1981 by EMI Records in the United Kingdom and on 6 June 1981 by Harvest Records and Capitol Records in the United States.  The album was their first with guitarist Adrian Smith, and their last with vocalist Paul Di'Anno, who was fired after problems with his stage performance arose due to his alcohol and cocaine use.  "Killers" was also the first Iron Maiden album recorded with the assistance of producer Martin Birch, who went on to produce their next eight albums up until "Fear of the Dark" (1992).

The Soundhouse Tapes: The Soundhouse Tapes is the debut EP by Iron Maiden, and features the very first recordings by the band.  Released on 9 November 1979, it features three songs taken from the demo tape recorded at Spaceward Studios on New Year's Eve 1978.  The three tracks - "Prowler", "Invasion" and "Iron Maiden" - appear in a rougher form than they would on the first Iron Maiden album and subsequent singles as they were all recorded in one session.

Eddie the Head: Eddie, also known as Eddie the Head, is the mascot for the British heavy metal band Iron Maiden.  He is a perennial fixture of the group's artwork, appearing in all of their album covers (as well as most of their singles) and in their merchandise, which includes T-shirts, posters and action figures.  On top of this, Eddie features in all of the band's concerts, as well as in the first-person shooter video game, "Ed Hunter", and the role-playing game, "Iron Maiden: Legacy of the Beast".

Eddie's Head: Eddie's Head is a box set by Iron Maiden, in the shape of the head of their mascot, Eddie and containing their first 12 albums remastered, from "Iron Maiden" to "Live at Donington", each with bonus multimedia material, plus a limited "In Profile" CD.  The spine of each CD has a part of the original cover art for "Iron Maiden".

Eddie's Archive: Eddie's Archive is a box set by British heavy metal band Iron Maiden, released on 4 November 2002.  The box, an embossed metal casket featuring the face of mascot Eddie, contains three double CDs, the Iron Maiden family tree and a shot glass.  The family tree is an updated version of the family tree that originally came with "A Real Dead One" in 1993.

The X Factor (album): The X Factor is the tenth studio album by English heavy metal band Iron Maiden, released on 2 October 1995 through EMI.  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.

List of songs recorded by Iron Maiden: Iron Maiden are an English heavy metal band formed by bassist Steve Harris in 1975.  The band's first album, 1980's "Iron Maiden", was written primarily by Harris, with vocalist Paul Di'Anno co-writing two tracks and guitarist Dave Murray contributing "Charlotte the Harlot".  The 1981 follow-up, "Killers", was written almost entirely by the bassist, with frontman Di'Anno contributing only to the title track, "Killers" (the North American bonus track "Twilight Zone" was credited to Harris and Murray).  Bruce Dickinson replaced Di'Anno after the release of "Killers", although he did not contribute any songwriting to "The Number of the Beast", released in 1982, which featured three songs co-written by guitarist Adrian Smith.  "The Number of the Beast" also spawned Iron Maiden's first UK Singles Chart top ten in the form of "Run to the Hills", which charted at number seven on its release.  It was not until 1983's "Piece of Mind" that the songwriting process became a more varied and collaborative approach, with just four of its nine tracks being credited solely to Harris, two to Dickinson and Smith, one to Harris and Murray, one to Dickinson alone, and one to Harris, Dickinson, and Smith.  The Dickinson and Smith-penned "Flight of Icarus" was the first Iron Maiden single to chart in the United States, reaching number eight on the "Billboard" Mainstream Rock chart.

Virus (Iron Maiden song): "Virus" is a single from Iron Maiden, released in 1996.  It is the first single since 1980's "Women in Uniform" that does not appear on any official Iron Maiden studio album.  It was, however, featured as a brand new track on the band's first ever career retrospective — 1996's double-disc "Best of the Beast".  It is the only Iron Maiden song to be credited to both of the band's guitarists.  It has never been performed live by Iron Maiden, but Blaze Bayley performed it several times in his solo career.  Lyrically, the song warns of rising business corruption in an increasingly Internet-dependent world.

Ed Hunter: Ed Hunter is a greatest hits album and video game released in 1999 by British heavy metal band Iron Maiden and Synthetic Dimensions respectively.  The game objective consists of following Iron Maiden's mascot, Eddie, through various levels depicting the band's past album covers.  The accompanying CDs have the group's most popular songs, as selected by fans on the band's official website.

Lord of the Flies (song): "Lord of the Flies" is an Iron Maiden single and second track on their 1995 album "The X Factor".  The song is based on the book and film of the same name.
