This is the band Iron Maiden. Twenty-three different members. Thirteen different lineups. Thirty-eight albums including 16 studio releases. Over 90 million album sales. Twenty-five hundred live performances. And all single-mindedly driven by one man who formed the band in 1975. We'll explain why Steve Harris is the greatest Heavy Metal songwriter of all time, why Iron Maiden is the greatest band in the world, and why Phantom of the Opera is their greatest song.
