While doing my list for the top 75, I used the ranking system and listened to songs that I was unfamiliar with. Which was the entire discography of Iron Maiden. I found some great songs in all of their albums, and those songs ranged from the reunion, the Blaze, and classic eras.
Iron Maiden has so many great songs that it's a shame they do not play these songs much at all live. To me, I feel it's a waste that Iron Maiden, or more the state of the music industry, has made these great songs to go by the wayside and never played live. That music industry idea of pleasing the casual fans and bringing in cash.
I would be all in for a reunion era set, or more, a set containing nothing but songs that are not the hit singles.
