Cynic - Focus. Amazing work on the parts of all the people involved. Unlike a lot of people, I think the vocals are really awesome, and bring together the whole concept very nicely. Talented musicians making something that unique, and flawless to boot, IMO. Perfect album.
Gordian Knot's self titled album. I'm always amazed at the compositional makeup of totally instrumental albums. It says a lot about the arranger, and I can't find a single flaw in that album. I'm not as fond of "Emergent," but the self-titled record has revolutionized my view of atmospheric arrangement and pacing in music.
A Perfect Circle - Mer de Noms. I wish Maynard had done this years ago. I love Tool, always have, but I knew he was capable of a much more ethereal sound, and anxiously waited for him to find musicians he clicked with to make this album. Unfortunately, I don't really feel that way about any of the other albums - individual songs, yes, but whole albums, no.
Virgos Merlot - Signs of a Vacant Soul. Been following the lead singer's career since The Devine, when Virgos hit I was struck dumb. "Beautiful Lie" and "Gain" are two of the most honest songs I've ever heard. Now Brett's in Dark New Day, and their stuff is pretty ****-hot, too, but not on par with Virgos Merlot, IMO.
I've got a few more, but those are my tops.
