Iron Maiden is one of my favorite heavy metal bands. The fact that they are not in the Rock and Roll Hall of Fame discredits that entire institution.

As a Brazilian heavy metal fan, you must be familiar with Sepultura! If not, here is their website: http://www.sepultura.com.br/ They were one of the original and I believe most popular of the bands coming from Brazil (Belo Horizante). "Refuse/Resist" by Sepultura is one of my favorite metal songs ever.
