Brave New World is really something.
Not only was it my first Iron Maiden album, it was pretty much my first real exposure to metal. Yeah, I'd heard some isolated songs, but I didn't always pin them down as metal or bother to listen to them. Metal was just noise to me.
BNW changed that. It was epic, its lyrics were reasonably intelligent by most standards of modern music, and the songs actually sounded like compositions. I couldn't imagine how it could possibly get much better.
What's really strange about that is that BNW has become one of my LEAST favorite IM albums, one I rarely listen to anymore. That speaks to the strength of their catalog, I think. It really does have some weaknesses. It carries the repetition over from Virtual XI, but I think it even more adversely affects these songs. Furthermore, some songs just sound like filler, and its closer is uninspiring. As far as I'm concerned, it's The Wicker Man, Ghost of the Navigator, Brave New World, Blood Brothers, and Out of the Silent planet are the only really amazing songs here. The rest I could do without, even if they're not bad.
As for TFF...
It's my favorite reunion album, and one of my favorites in their entire catalog. I actually prefer the first half to the second--I think it rocks just as hard as their 80's material, but has the more intelligent lyrics the reunion albums have consistently managed. That said, Where the Wild Wind Blows is one of the greatest things this band has ever done, period. It alone is worth the purchase price of the album.
Loved DoD, probably more than BNW. AMoLaD is my least favorite reunion album, but I respect it. Gives me the same vibe as The X Factor, but I don't enjoy it nearly as much.
