This was the first Dream Theater release that I was waiting for to come out, because I had become a fan sometime between SC and BC&SL came out. I bought it rather quickly after it came out and, initially, I was very happy with it.
However, when I first heard ADTOE, I was literally blown away and I, when I listened to BC&SL again afterwards, I found it lacking in many areas, which mostly make ADTOE that enjoyble, the first and foremost of these issues being the lacking balance of guitar and keyboards on this album.
Still, I don't understand why some people seem to hate it that much. It's still a very good album, and compared to very many other bands, it's even a masterpiece.
A Nightmare to Remember: Like many people, I love the beginning, but I find that the instrumental section drags on for a while too long. Portnoy's growls don't really bother me, but I don't miss them either on ADTOE. The intro, up to "Beautiful Agony" is
A Rite of Passage: This song is catchy, but too standard for me to truly enjoy. The chorus is cool, and Petrucci's soloing is great as well, but Jordan's soloing doesn't hold that standard.
Wither: I like the restraint shown with this song, though I find that it is quite standard as well. Especially the repetitiveness (DT has often shown that they don't need to have identical verses - why do it here?) irk me. The solo is stellar, though.
The Shattered Fortress: Mediocre track. It is fairly enjoyable in the middle, but the soloing is too long, imo. The "Responsible" part is great, probably the best moment of the track. One a side note: why does it end with "The Glass Prison" intro - isn't the goal to leave alcoholism behind, not to begin anew?
The Best of Times: I can't understand why people dislike the song's lyrics. I find that they capture the subject perfectly. The Rush-esque intro is great, just as the softer parts later, though the key part in the middle wouldn't have been needed, really. Oh, and even though pretty much everyone agrees on this: DAT SOLO!!!
The Count of Tuscany: Great song. The lyrics don't bother me, they add to the fun, imo. The soft part in the middle could have been shorter and I always skip the noises at the end, but other than, this track is truly great.
There you have it. All in all, a good album, but ADTOE (and of course, all the other great albums like I&W, Awake, FiI, ACoS, SFaM and SDoiT) blow it out of the water, ranking it as one of DT's bottom three albums - that doesn't stop it from being good, because I love most of DT's discography anyways.
EDIT: After listening to it twice more, I find it to be better than SfaM, but only just.
