Hailing from the East End of London, Iron Maiden turned heavy metal into an art form during the early 1980s and beyond, combining their formidable guitar barrage, incessant pounding rhythms, and a flair for the spectacular into a long, acclaimed career. The band was formed bass player Steve Harris on Christmas Day, 1975, during a period in which British metal music was woefully unfashionable. Early progress was slow until Paul Di'Anno joined as Iron Maiden's singer in 1977. Three years later, the band's self-titled debut album peaked at Number 4 in the UK, earning the group an audience across Europe. However, it was when ex-Samson singer Bruce Dickinson replaced Di'Anno in 1981 that the seeds were sown for Iron Maiden's enduring classic album, The Number of the Beast, which kickstarted their reign as one of the UK's most successful bands. The band's next three albums all went platinum in America, while 1990's "Bring Your Daughter...To the Slaughter" — a track from the band's eighth studio record, No Prayer for the Dying — became their first chart-topping single in the UK. Despite various personnel changes and a string of solo projects from the multi-talented Dickinson, Iron Maiden's appeal endured through the first two decades of the 21st century, too, with releases like 2010's The Final Frontier and 2015's The Book of Souls both going gold in more than six countries. 40 years after their beginning, they placed their 2021 album Senjutsu at Number 2 on the UK album chart and Number 3 in the U.S. and going to Number 1 in half a dozen countries around the globe. Hailed as a dynamic act in concert, Iron Maiden has released a dozen live recordings.
