Random thoughts:
- The Book of Souls is probably the most sprawling and diverse album they've done so far. As an incorrigible ecclecticist, I like that.
- "If Eternity Should Fail" is, if nothing else, the most offbeat Maiden opener ever, save perhaps for "Sign of the Cross". I like it a lot, though I'm really not sure about the spoken word bit at the end.
- The Janick epic has been a standing feature of the reunion albums, but he has really outdone himself here. "The Book of Souls" is stunning, the best he's written since "Dream of Mirrors", maybe his best ever. They have to play that one live.
- Nicko has rarely if ever sounded better. At times, like on "When the River Runs Deep" and parts of "Empire of the Clouds", he is the main attraction. I realize that I may have been underestimating just how much the rhythm playing contributes to my preference for Maiden over any other metal.
- Speaking of "just", it continues to be Steve's filler word of choice when he needs another syllable: "Are you scared to look inside your mind / Are you worried just at what you'll find". No, wait, I mean: "Step inside my inqusitive mind / Are you scared at just what you might find". Opinions on that song seem to be split; I will tentatively side with the camp who likes the instrumental part more than the vocal parts, which suffer from rather uninspired melodies.
- That said, vocal melodies are generally very strong, better than on The Final Frontier, and Bruce mostly sounds good.
- After several listens, "Shadows of the Valley" is the one song that still hasn't made any lasting impression. Not unenjoyable, but undistinguished.
- The last three songs are the most intriguing to me. "Tears of a Clown" has the best melody of all, underpinned by more great drumming. It's one of the most perfectly crafted songs they've ever done. "The Man of Sorrows" is more adventurous, with some parts that sound like nothing Maiden has done before. I really like that, apart from a brief return to the "as we look..." melody after the instrumental mid-section, it never repeats itself. The disaster ballad at the end is pretty neat as well.
All impressions subject to change at any listen.
