Editor's note: Iron Maiden saturates the brains of their fans with multi-guitar attacks, unforgettable vocals and endless energy. Considered by many to be the best pure heavy metal band ever, they helped forge the genre and create the sound that we now define as metal. They also win our vote for non-rap lyrics most likely to annoy parents (we refer you to "Bring Your Daughter to the Slaughter"). In sum: Tipper Gore's worst nightmare, legendary metal band, amazing wallpaper collection. Check it out.
