One thing that many bands have done, but Maiden haven't yet, is to revisit a classic album and play it in its entirety. Basically what they did with AMOLAD, but with one of the golden era albums instead.
Usually I'm not a big fan of such an approach, but for most albums this would mean that at least one previously not played song would resurface (which is always awesome imo!). Also, I'd rather get something like SSOASS in its entirety than a "best of best of tours" kinda tour like the current one. The current show was awesome, but I don't need to revisit something like that, I enjoy the post-80s material too much for that.
Ok, I think the three most likely candidates for this kind of tour would be TNOTB, SSOASS, and Powerslave. I just don’t see POM ever getting a full play through, plus it was heavily featured on LOTB. Then SIT just had a big tour. Killers and the debut are highly unlikely simply because I believe they retired most of those songs in 2005, three Killers songs are currently in the set, and since Di’Anno’s death Bruce has stated that they will never play Remember Tomorrow again.
Which leaves my three choices.
TNOTB: It’s their breakthrough album with lots of hits and they’ve played most of the songs live. It would also give them an excuse to bring back Total Eclipse. The only issue with this album is that the band doesn’t really like Invaders or Gangland. I think Adrian likes Gangland, but I don’t think his influence alone could convince the others.
Powerslave: Arguably their best album. Two of their biggest singles and the last two songs are fan favorites. The middle section of the album has been neglected live and there are some fantastic songs that most fans would love to see live. Only issues with this one is that The Duellists and Back In The Village are pretty tough songs on vocals and guitar plus this album has been represented in the set a lot over the past 25 years.
SSOASS: Also arguably their best album (though I personally disagree). Very popular with new and old fans. Would work well live since there is a loose narrative that runs through the album. Only The Good Die Young is a song that Steve has wanted to play live and this would be the best way to do it. Issues with it: Infinite Dreams is a tough song and they already did a retrospective tour for it.
Conclusion: SSOASS is the most likely because it would feel very cohesive live and it is popular both with the band and the fans. TNOTB has two songs that we know for a fact that the band dislikes. The Powerslave staples are a bit overplayed and two of the songs are bit complicated.
Of course I could be dead wrong in my takes.
This should be a thread on its own. I really like this concept and I’d love to see other people’s opinions.
