This is a highlight in Root's discography. Never before had they been this dark and technical in their approach. A superb mixture of hellish atmosphere and progressive thrash (actually quite a few of the riffs remind me of Hell Awaits). No one can beat those wide open slightly atonal Blackosh guitars...the man is a master, how he can turn those Voivodian chords into a baroque, gothic nightmare is beyond words, and beyond me! Big Boss goes off (as usual), and special mention has to be made of Evil's drumming. I can't say enough good thing's...he's just in the pocket and oh so creative (especially during Theriak, holy shit!!) A wonderful album that reveals itself to be a true masterpiece after repeated listens.
