1. likely MP was the man most responsible for the bloat in aughts DT. I say likely, I could be wrong.
He is responsible. When anyone, anywhere, reaches out for bloat. He wants his hand to be there.
I wouldn't say he was "responsible," because JP likes to write that way as well. But I would say he was a MAJOR contributor.
2. Do you prefer DT to write that way, more concisely, or do you miss the more epic-length tracks? I like the concise approach but wouldn't mind 1 huge epic per album.
It really depends. As MirrorMask said, it's on a case-by-case basis. I have enjoyed the Mangini-era output. I do feel that some songs, especially on the last album, could be a bit longer and given a chance to breathe a bit more. But at the same time, they didn't
need to be any longer. I like that on ADTOE, for example, you had plenty of songs that were a more "traditional" song length, or at least close to it. But then you also had four songs that went over the 10 minute mark.
3. Also gone in the songwriting are obvious nods to other bands like Muse, U2, etc. Fine by me.
Eh, not really. The nods are just different, and are perhaps less-known bands. There has been a TON of Rush influence--perhaps more than any other 4-album stretch. And other bands as well, like Red, for example.
4. Also gone are lame attempts at harsh vocals and such. Again, this is a good thing considering their singer is 56 this year and has compromised vocal chords.
Well, I'm not sure what you mean about vocal "chords," since that is an impossibility. A singer is only able to sing one note at a time, and cannot really sing chords, unless you are talking about layering multiple parts in the studio mix.
As far as "harsh" vocals, do you mean just by James, or do you mean the stuff that Mike was layering in? As for the latter, that is gone for the obvious reason that we don't have anyone left in the band who (1) is a big fan of grittier vocals and actively
wants them in DT songs, and (2) can actually pull them off. As far as James singing grittier, well, that's just age. And the fact that he knows he cannot sing that way without destroying himself. But that's fine. I mean, listen to his live vocals from the first two tours after he had joined. That was perhaps the grittiest he has ever sung. And while it could sound cool, it could also sound really bad at times too. But his injury caused him to
have to move away from that, at least in a live setting. Yeah, in studio, they found ways to mimic that. But he stopped doing it live a LONG time ago.
