Just a few random thoughts..
The one opinion that is surprising me a little, is many peoples indifference to FAS. It was always slated as an album and concert opener, and I think it kicks off the cinematic feel perfectly. Not to mention adds a great deal of atmosphere to TEI, making an impact sounding one-two punch..
Enigma machine is good. Nay, real good. Like any DT music, songs can take a while to sink in, but for anyone not feeling it, just go have a listen to SOC again.. Good main riff, but a lot of filler, and longer than it needs to be. EM however, is shorter, and now some of the melodies have sunk in, always interesting. The slower bit is very COTTuscany too..
I like the Easter egg music a lot, but not entirely sure it necessary to make it a song by itself. It's very Far From Heaven sounding, so I just feel it serves it's purpose already as the 'closing credits' moment of the album..
Overall, just a beast of an album. Some of the best songs and riffs going round, and IT is as fine an epic as any. The orchestra and outtro are amazing, and I actually love the changeup back to the heavier section - it's like 'yep, we can do beautiful, but in a split second, we're gonna change tact and melt your face bitcheees.. ;-) Seriously amazing all round!
