Not to turn this into a Maiden discussion, but I feel like it was a consequential decision to do a small greatest hits tour and then go all out on a new album focused tour. The Brave New World tour setlist is wild. Of the first 11 songs, only three are from the 80s.
We're going to get something similar with this upcoming Parasomnia tour maybe. Obviously they are playing A Change of Seasons, but we're also getting the full Parasomnia album and a full set worth of other material. I've seen a lot of speculation that they might just throw in the songs that they've been playing in Europe, although I would love to see them go a little bolder.
