The Mars Volta - Octahedron
To me, their weakest and least remarkable release. Not bad by a long shot, but it's essentially an entire album in the vein of their "single" or "ballad" tracks off of their other albums.
David Bowie - Never Let Me Down
At least Tonight had some catchy songs, this album was generally a boring slog.
Dream Theater - The Astonishing
I've expressed my distaste for this album too many times than I care to count, but it's just too long and too uninteresting both instrumentally and conceptually.
Godspeed You! Black Emperor - "Luciferian Towers"
As a big defender of Asunder, Sweet, this one was a bit of a let down. Just sounds like Godspeed going through the motions.
King Crimson - Three of a Perfect Pair
A less interesting version of the previous two albums. Not a bad album, but Fripp has clearly done better, even in this phase of the band's career.
Yes - Heaven & Earth
I can't even remember half of what I listened to here. Just sleep-inducing soft prog.
Agalloch - The Serpent & The Sphere
This came across as fairly generic folk metal as far as Agalloch goes. Some of the songs just drag on and on and with little pay off.
