Now that you guys mention it, the DT-influence gets more and more prominent the more I hear it, and given the band's participation in Portnoy's Shattered Fortress, it definitely makes sense why they might take inspiration from those songs and music and use it to mold the songs for Vector.
Also surprised by the DT comparisons in a way. I mean Veil has some VERY DT-esque stuff, and there's one short section in Puzzle Box as well (the 2nd verse) but otherwise I don't hear any DT at all.
I absolutely love the album, and it'll probably be my favorite when I do the ranking (I always wait until the listens of the new album have approximately reached the listens of the rest to rank it)...
Having quickly told the personal context of how I'm feeling with the album, there's one tinny thing that it might easily represent yet another
easter egg within this album and of which I haven't read or heard anywhere.. It has to do with all what I quoted (specially the bolded parts), and I obviously wouldn't mind writing about this if I weren't so sure..

So.. I don't know if they've done this on purpose, like the references to other Haken songs or all the other things related specifically with the concept of the album (like the section of TGD from 1:53 to 2:09 in which the riff structure/time signature resembles the Rorschach's images)... but there are two sections that are VERY similar to other "two sections" of two DT songs (which is why I'm a bit surprised no one here mentioned it or realized the similarities, being this a DT forum after all).. I say "two sections", because they are actually four, only that splitted into two different DT songs.. No surprise here keeping in mind the MP's Shattered Fortress shows they've played lots of times just before writing Vector... the songs are The Glass Prison and This Dying Soul.. As songs that are part from the same "saga", they share a few sections, and two out of those are the ones that matter..
First, in Puzzle Box, the structure of the section from 2:44 to 2:59 is not only very similar to TGP 11:39-12:46 and TDS 8:57-9:30, but it's an structure that I don't recall Haken has ever used before -the "structure" is basically intercaling one particular riff with "the" or "a" main riff, which gives you the feeling that the back and forth between the two riffs is never going to finish nor let the song move to another instance.. That "particular riff" is also almost identical to the respective DT ones, almost like being a mixture of the two..
Second, and this one is way more obvious because it involves lyrics, but also more interesting and similar than the previous, the excellent chorus of Veil and its "Save me (...) Teach me (...) Hold me (...) Guide me (...)" not only is textually very similar to the "Help me (...) Save me (...) Heal me (...)" that appears in both DT songs, but the melody is surprisingly almost the same that both DT sort-of-choruses, and, again, it seems like a mixture of the two.. Always talking only about the melody (the bases and time signatures are different in the three mentioned songs/sections)...
structurally speaking the choruses of Veil and TGP are almost identical, and they even coincide in having an extra longer phrase in the middle of each "xxxx me";
musically speaking, Veil's and TDS' lines share the exact same three main notes! (B-F#-G)
Maybe there are other sections like this, who knows.. And FWIW, I didn't purposely searched any of this.. I just noticed it while listening to the album, which definitely prog-rocks the way it is anyways...
