Iron Maiden was first formed in 1976 by bassist Steve Harris, who would soon join up with rhythm guitarist Tony Parsons, drummer Doug Sampson and vocalist Paul Di'Anno. Before finally obtaining a record deal, the group played in local areas throughout the '70s, receiving a fair amount of London air play. Parsons was replaced with Dennis Stratton, and the band made its record debut in 1980 with their self-titled Iron Maiden album. Although the release was recorded in a hurry, it was nonetheless a hit in the U.K. due to the single "Running Free." Iron Maiden's 1981 follow-up, Killers, displayed a harder approach to their music than before, and also saw the replacement of Stratton with Adrian Smith. Due to his uncontrollable alcohol addiction, Di'Anno was forced to part company with the group and would soon be replaced with vocalist Bruce Dickinson in 1982 for the band's ground breaking release, Number Of The Beast. This album, boasting such songs as the title track and "Hallowed Be Thy Name," would come to be known as one of the greatest rock recordings of all time. Since the unexpected worldwide success of Number Of The Beast made them international rock superstars, they changed very little of their style for their next album, Peace Of Mind. They undertook two major tours before recording 1983's Powerslave, which would go on to be another cult hit. The product of Powerslave's 11-month tour was 1985's Live After Death, a double live album the featured all of their biggest hit singles.

By the release of Live After Death, Iron Maiden had already established themselves as a powerful and unique metal band. Their long-awaited 1986 supplement album, Somewhere In Time, showed a bit of departure from their past releases,

showcasing the use of synthesizer guitars and songs more relevant to the same themes. 1988's Seventh Son Of A Seventh Son, a concept album like that of its predecessor, featured the singles "The Evil That Men Do" and "The Clairvoyant," and soon became Iron Maiden's most critically acclaimed album since Number Of The Beast. After another exhausting tour, Smith departed and the band took a one year hiatus. With new guitarist Janick Gers, they resurfaced with No Prayer For The Dying in 1990, a record that returned to the classic sound the group used when recording their earlier releases. One of the album's singles, "Bring Your Daughter To The Slaughter," was granted the Golden Rasberry Award for Worst Song Of The Year, but it nonetheless gave the band its first #1 U.K. hit. By the time the group finished their 1991 tour, Dickinson expressed desire to leave and work to promote another band he had founded, the Skunkworks. Fear Of The Dark the band's last album with Dickinson, debuted at #1 on the U.K. charts and became one of their biggest selling albums to date. After their supporting tour, two live albums were released in 1993: A Real Live One, which contained live versions of their newer hit singles, and A Real Dead One, which featured the more "classic" Maiden songs live. Dickinson's replacement, Blayze Bayley, marked his debut in 1995 with The X Factor. While the record failed to chart as well as some of its predecessors, it was still a minor success in England. Iron Maiden marked the end of 1996 with Best Of The Beast, a double compilation album. In 1998, little interest in theVirtual XI album prompted Bayley's termination; Dickinson and Smith returned to the band for a tour in 1999 and a new album, Brave New World, the following year.
