"A Nightmare to Remember," "The Best of Times" and "The Count of Tuscany" are some of their best songs of the 00s.
"A Nightmare to Remember" is a fantastic song, with a great mellow middle section, some cool vocal melodies, and some seriously badass playing by John Petrucci throughout.
"The Best of Times" manages to be beautiful, melancholy and wistful all at the same time, and without being cheesy at all. JP's solo at the end is ridiculously great.
"The Count of Tuscany" is marvelous, despite the corny lyrics. Great intro, and when it picks up right before the first vocals, that is one of the best riffs they have written in a long time. Love, love, love the acoustic-driven vocal section near the end, and JLB's "woah"'s during the outro are just magnificent.
"Wither" is a wonderfully catchy song.
"A Rite of Passage" is good; good bridge and chorus. I sometimes lose interest once the second chorus is over, as I think the extended instrumental section isn't overly memorable, but still, good song overall.
"The Shattered Fortress" is easily my least favorite. I feel like too much of the song is taken from riffs and melodies from the previous AA songs (instead of it being a song with a few of them dotted here and there), and the new stuff isn't that great. Not a bad song by any means.
Overall, 4/5 stars. Not as great as the Big 3 (I&W, Awake, SFAM) or 6DOIT, but a massive upgrade over the previous three. If it ages well, I could see it being my 5th favorite DT record (although comparing it to FII will be tough, as FII's highs are higher, but its lows are also lower).
