The most impressive curveball Maiden has ever done and an instant attention-grabber right from the song length, the title and just how very different it is. It's so disconnected from everything they've done up to this point (except for perhaps Journeyman, but that one kinda failed) and it stands out for those reasons. There's only one part of this song where the familiar songwriting tricks of Maiden make their presence known and that's in the instrumental sections and the following fast verses. Everything else doesn't really feel like Maiden, but more or less a Bruce Dickinson solo song disguised as Maiden.
So, is it fair to call this one of the best Iron Maiden songs? I wouldn't really say so, but this is still a masterclass work of songwriting in its own right. The lyrics, which I'm sure everyone's mentioned, are some of the best Bruce's ever written and the song certainly seems written around them. Because the structure is wholly dictated by the lyrics which is certainly a feat since they pull it off with such ease. However, I do agree that some parts do go on a bit long. There are certain guitar riffs (yes, that one) which seem to repeat just a few too many times. They're memorable for that reason and they're not bad riffs, but you do kinda want back to the much more dynamic musicality of the parts before and after this guitar-heavy middle. Yeah, I do consider this middle bit the weak link of the song. Bruce sounds remarkably strained in the fast verses here, something worth noting since his performance is freaking incredible otherwise. It's a bit disappointing, since the middle is where all the disaster is happening. The solos are not particular to my liking either.
But the rest of the song is just perfect. The last few minutes, in particular, are some of the best music I've ever heard, not just by Maiden. It truly feels like you've come to the end of a very lengthy journey (fitting, considering the 18 minute length) and you leave feeling very satisfied.
Unfortunately, this is NOT a song I would use to introduce people to Maiden with. Again, it's so very different from everything else in the catalogue that it can be slightly jarring going from this to other usually-considered amazing songs. Like the title track of the same album Empire is on. I like that one more, because it's a Iron Maiden song. This really isn't. And it does hurt the album, because as Diesel pointed out, it feels like the entire album before Empire is just foreplay. This steals the attention away from every other song on the album. Everyone's first listenings of this album must have been "Yeah, this album is pretty great so far, but I'm really looking forward to hearing that final one". And since it's the final one, it's the one to leave the lasting impression as well. And since it's such a show stealer, you will probably only think of it and not some of the others. The Red and The Black, despite being 13 minutes, is a prime example of this. There are only two songs on the album, which I think gets even remotely near the same amount of attention and hype as this one, and that's Bruce's own If Eternity Should Fail and the title track.
And really, that's just a bit disappointing. Still, even with those issues, this is an easy 10/10.
