Iron Maiden is more than just a heavy metal band. It’s an experience. Since coming together in 1975, the U.K. band has left a mark on their dedicated fans, providing a concert experience that they will not forget. Long considered one of the greatest live acts, the Maiden released their 16th studio album last September. Maiden recently postponed touring until lead singer Bruce Dickinson fully recuperated from a cancerous tumor that was removed from his tongue. If that’s not hardcore, we don’t know what is.
