Easily considered one of the most successful heavy metal bands in history, Iron Maiden is hitting up Europe and of course, their tour would be incomplete without a stop in Poland. With over 38 albums released and 100 million copies of their albums sold worldwide, it's safe to say this British band is an object of mass consumption—so expect tickets to be expensive and to go fast. The concert will be a blast from the past featuring mostly the tracks that brought the band fame back in the 80s, but some new and surprising tracks will also be thrown into the mix.
