I read/heard in interviews that Mark wrote the lyrics to Godspeed. And it was one of a couple. They mentioned another. I forget which one. I'm with you in that I like the songs to take me somewhere (ala Blackbird, Fortress). But I'm also fond of the shorter style if it is meaningful (and most AB songs are). Take "Show Me a Sign" for example. Epic, story-like. I feel like they captured and represented that well on Walk the Sky. I think they expertly made many of the songs on this record really have a bit of that "story" feeling, without the length. Not all of them, but the title track, Dying Light, Clear Horizon, and Native Son come to mind. Would they be "better" if extended? I'm unsure. I think a sweeping trade-off, harmonized, or single solo around the 30-second mark added to most would have increased the emotion of the tune. But did they really NEED something more? I'm not sure they did. I just don't know. I'd have to hear it and compare to be sure, obviously. But they way they did it feels...complete to me.
Now, that said, do I want a couple of seven-minute tunes on the next AB record - yes. But the flow they achieved with this record...I just don't think, after listening to it a ton now, it is really necessary to lengthen the songs in any manner. The solos appear, just in different spots and are shorter. And the arrangements are still a little quirky, so it's not like all the songs are your standard verse-chorus-verse-chorus-chorus format for radio, you know? It's deeper. As AB should be.
You have seen enough of my rambling by now to know I fully agree on the mixing. I hear what you hear, and would like a change from Elvis. I don't even think you need to change producers or engineers. Just send the recordings to someone else to mix. Just for a fresh take. But if the band loves it, then it is their record, not ours. And I do love Walk the Sky, and so I'm fine with it the way it is. It's not like its washed out like TLH. LOL. I'll just cross my fingers again that the next album they do break away at least for the mix.
