Let's see how far some speculation on the individual tracks can take me.
1. If Eternity Should Fail (Dickinson) 8:28
Unless this follows the same idea as Final Frontier did, with a four minute intro followed by a four minute rocker, this is definitely going to be a departure from the last albums. Bruce is essentially the most fearless of Maiden's songwriters, and I would trust him to come up with anything. Having said that, the last sole songwriting credit he had was on Tears of the Dragon. And that's 21 years, four solo albums and six Maiden albums ago. Bruce's recent songwriting output was diverse enough for me to say that we can expect anything here.
2. Speed Of Light (Smith/ Dickinson) 5:01
Short Smith/Dickinson tracks used to be staples on Maiden albums, but they've become significantly rare. In fact, the last one we had without Steve's meddling was Hooks in You. Having said that, most Smith/Harris/Dickinson numbers are more on the rocky side of things, although there are notable exceptions. But if any song on this album will sound anything like The Wicker Man or Two Minutes to Midnight, I bet it's going to be this one.
3. The Great Unknown (Smith/ Harris) 6:37
In most recent cases, Steve took on the role of arranging other people's composition fragments. Which is why songs like Mother of Mercy, Isle of Avalon, Paschendale or Different World, despite having H's clear handwriting, have Steve's name on it as well. This might also be one that will have more of a traditional Maiden sound to it.
4. The Red And The Black (Harris) 13:33
It's an interesting tendency of Steve's solo compositions that they got longer on each album since Blood Brothers. They also all had a very distinct, recognisable sound, sing-along melodies and all that, and I sort of doubt Steve will radically alter this with this one. Nevertheless, When the Wild Wind Blows was already a significant departure in terms of composition while still staying recognisable in its sound. I expect a next evolutionary step here. If it is indeed going to be about the Stendhal novel, it's nice to see Steve tackling literature again.
5. When The River Runs Deep (Smith/ Harris) 5:52
Same comments as for The Great Unknown.
6. The Book Of Souls (Gers/ Harris) 10:27
With this running time, I think this is going to be the most likely candidate for the soft intro/verse/heavy part/extensive soloing/soft outro structure that we know so well from this pairing - Dream of Mirrors, Dance of Death, The Legacy, The Talisman, etc. I'm fine with that, mind you. But somehow I have a gut feeling that this one will get the most flak.
7. Death Or Glory (Smith/ Dickinson) 5:13
Same comments as on Speed of Light.
8. Shadows Of The Valley (Gers/ Harris) 7:32
I doubt that what I said about The Book of Souls applies to this one as well, given it's relatively short running time. This might be more of the Gers/Harris team we know from songs like The Mercenary or The Pilgrim.
9. Tears Of A Clown (Smith/ Harris) 4:59
Again, this might be more of an Adrian composition arranged by Steve. I dislike the title a lot, though. Could turn out to be a ballad.
10. The Man Of Sorrows (Murray/ Harris) 6:28
Murray/Harris almost always means extensive, melodic soloing, few vocals and longer instrumental sections. While most songs in question (e.g. Thin Line, The Man Who Would be King) are significantly longer than this, Age of Innocence would be a reference point to a shorter piece with similar writing.
11. Empire Of The Clouds (Dickinson) 18:01
I have absolutely no idea whatsoever about what to expect from this.
So the bottom line is that with some songs, I have an idea of what they might be like, while others leave me completely in the dark. But in general, it's all speculation, and I'm just going to wait until I hear the songs. If anything, this has me quite excited. And I'm quite happy to see that Maiden are still willing to take risks. I love the Eddie, although I'm not sure yet about what I think of the minimalist approach for the cover.
