The Number of the Beast is the third studio album by British heavy metal band Iron Maiden, released in March 1982. It saw the debut of vocalist Bruce Dickinson, and the final appearance of drummer Clive Burr.
The Number of the Beast met with considerable critical and commercial success and was a landmark release for the band, becoming their first album to reach No. 1 in the UK Albums Chart, and be certified platinum in the US. The album also produced the singles “Run to the Hills” and “The Number of the Beast“, the former of which was the band’s first top-ten UK single. The album was also controversial – particularly in the US – due to the religious nature of its lyrics and its artwork.
Since the release of The Number of the Beast and its subsequent tour, The Beast on the Road, “The Beast” has become an alternate name for Iron Maiden, and was later used in the titles of some of their compilations and live releases, including Best of the Beast and Visions of the Beast.
