ADTOE - The best of the post-Portnoy era, if anything because it's closest to the Portnoy-era sound, Mangini had no involvement in the writing. Sound is terrible. Songs have great parts and I over-listened when it came out, but it feels a little DT-by-numbers now.
DoT - Fun album. The whole is better than the sum of it's parts, imo. Sound is OK, a little too compressed, but Rudess is up front in the mix.
DT - The sound production is very cold to me, and and the mix is too hot. Makes it hard to enjoy the music. While it has amazing sections, especially the beautiful ambient and orchestral sections, I don't feel like the epic Illumination Theory is a cohesive piece of music. My favorite part of the album is the hidden track at the end *shrugs* the only song I feel works on this album is Behind The Veil.
The Astonishing - So many mixed feelings about this album, and it's way too long. Best sounding mix of the Mangini-era band. After almost 5 years of this album existing, while I think the first overture is one of their best things under the DT banner, I'm just not into much of the material, even the better tunes. TA is my least favorite DT album for me.
All are basically in my bottom 5 Dream Theater albums, with the debut somewhere in there. I feel like Portnoy grounded a lot of JP and JR's ideas. As opposed to describing the music as "too" technical, I feel like modern songs sometimes suffer from weird flow and/or awkward transitions, as crazy ridiculous as they be to play/perform, from a listening perspective it just doesn't vibe with me as much. I also haven't been into whatever sounds or patches Rudess has been using lately, though I thought some cool stuff popped up in DoT and he has been using more organ since Portnoy left, which is good. Maybe it's because he's getting older, but I'm not into whatever filter or reverb JLB uses. I miss the clean, dry vocals of the 90s/00s albums. I remember listening to either Six Degrees or Train of Thought a little while back, then put on DoT and I turned it off within a couple of songs because I couldn't listen to the vocals right after listening to the older album.
