I am a few listens through and it is a lot to take in at once (not a criticism, just a fact). There is no way I could offer a thorough critique of this without many more listens. I would warn to people to be cautious of people proclaiming definitive truth statements good or bad about this for awhile until people have really had time to get through it. This is not an album for the distracted to put it on in the background while they are doing 3 other things. This is an album that us slightly older folks will remember as one you sit down with headphones and the lyrics and absorb.
Some simple first impressions; this is a concept album/rock opera first and foremost. SFAM is a DT album, that happens to be a concept album. So the structure and songs are much more in service of a double cd rock opera than songs on their own. Not a criticism, more just a decision they made to write with the album taking precedence over stand alone songs. There are amazing moments all over it. The test upon further listens is to see if all the moving parts can come together. I am optimistic, though like I said up top, it is going to take some real time and energy to determine that.
The key to me is that they spread their wings and made a truly progressive album. A quality retread album would have been acceptable at this point in their career. But they went for it. You can tell that creating music still get the juices flowing as much now as it ever did for JP & JR. The fact that they tried something this radical is a victory. As I mentioned before, they put out a complex album you really need to dive into in an era of listening to Mp3's while working and looking at Reddit etc. This album is going to come together for some people and it won't for others, but the fact they did not take the safe path should be commended.
