Query: Best Since Powerslave !!!!!!

I have been a Maiden fan for 20 years. Been through their ups and downs. Hated when Bruce Dickinson left and loved it when he came back. ( Blaze sucked anyway) I don't expect them to ever make another album like Number of The Beast or Powerslave but this comes pretty damn close. The guitars are heavy and Bruce Dickinson proves that he is in the top 3 voices ever to come out of England for metal.(Dio and Ozzy of course need consideraton) This band is one of the greatest ever and will live on for ever. They stay true to their fans and their music. As a long time follower, that is the mark of a true metal band. Up The Irons Boys !!!!!
