By way of my brother Jim: Who could have ever imagined that one of the best heavy metal bands of all time, Iron Maiden, would receive a tribute in National Review Online? No matter where you fall within the political spectrum -- at the conservative end or at the Chris Ferris end :-), John J. Miller perfectly captures the essence of Iron Maiden in this article.
Powerslave is indeed an incredibly good album, but they've also put out two really good CDs fairly recently: Brave New World (2000) and Dance of Death (2003). Jim, my daughter Erin, and I saw them last year at the Worcester Centrum on their Dance of Death tour, and they were damn good.
And coincidentally, just as I finished writing this, the song "Journeyman" from Dance of Death came on in my iTunes random play -- cool!
