I voted "Among his best" a few days ago, but I just haven't had a chance to respond to this thread quite yet, until tonight...
After a year of this album, even though I haven't listened to it in a couple of months (as I've kind of rotated out any Neal Morse music from my listening), it has left a greatly positive impact on my musical memory, and I can definitely say it's one of Neal's top 5 albums, up there with the likes of The Whirlwind, Snow, and One (not sure what the fifth would be for me...hmm, maybe ? or perhaps Testimony 2, which has "Seeds Of Gold" and that's worth a lot on its own).
I think what elevates this album above some of Neal's other works is the collaborative efforts strewn across the album, between musical, lyrical, and vocal contributions from nearly the whole band, which give it a huge depth and width that some of his works don't quite fill. The multiple vocals remind me of some of the best parts about Transatlantic and Flying Colors, while injecting the musical styles and influences of the likes of Eric and Bill to create something a bit different from Neal's other two bands.
It wasn't quite an instant classic for me, but having had a year since then, I can definitely agree it's a classic now, and probably one I could recommend to new fans of Neal's if they're looking for something more recent. I'd say TSOAD succeeds where, in the eyes of some fans, Snow and Testimony fail (in some regards), and even though I *love* Snow, there are moments on TSOAD where I feel like the band outshine that album.
It can be a bit cliche to ask "where could they possibly go next?!" after a new album comes out, but after TSOAD, I truly have to wonder what they could accomplish as a band! After nearly two decades of writing prog albums, having the Neal Morse Band come into Neal's life as a unique identity really helped him freshen up his music, and I'm anxiously eager to see what the third NMB album will be like.
