The cultural impact of Maiden's music, at least as I perceive it, is that it can be educational. Best example: Until hearing Maiden's version of Rime of the Ancient Mariner in the eighth grade, I had never read Coleridge's poem. Shortly afterward, I did a lengthy independent study school project on Coleridge's poetry. I more recently read an excellent two-volume biography of Coleridge. That is just one example -- the band's lyrics over the years have introduced me to a number of historical and literary subjects about which I previously knew little or nothing. Here is a very nice article from the National Review, a conservative American political magazine, and hardly the typical forum for an article about a heavy metal band:

Of course, sometimes Iron Maiden's lyrics can be miseducational -- for example, elsewhere on this Board is documented the historical inaccuracies in "Alexander the Great" -- but if Maiden's lyrics stimulate you to further reading and you figure out the true facts on your own, there is inherent educational and cultural value in that, even if the lyrics may have got it wrong. I will leave it to others to explain the historical value of Maiden's work. In a shameless and self-aggrandizing plug of an earlier (relatively unread) thread I recently started, there are also a remarkable number of literary references in Iron Maiden's work, which I attempted to summarize in a "reading list." Here is the link:
