"This is the third album from Georgia psych-sludge trio Zoroaster, and boy have they done it this time. Put this album on and you're in for an hour of some powerful vibrations. Unlike its predecessor, which was furiously bare-bones sludge, Voice of Saturn takes that heavy base and liberates it to its intended cosmic pathway. From the kicker track "Spirit Molecule" these guys demonstrate that being outer-limits spacey doesn't mean you have to sacrifice the ball-breaking menace of the music."
"As the last album pulverized well within the confines of the sludge formula; slow tempos, crushing repetition, epic Sabbath inspired riffery, with smatterings of psychedelia, this effort finds these dour druids expanding on said formula, injecting more melody and trippiness, with refreshingly unexpected results. The space rock drones are everywhere, in abundance, and add to the variation. It enhances and elevates the songcraft, bringing to mind a bad mushroom trip while staring at the sun. And the riffs, oozy and foreboding, not straying to far off the doomster path, but providing the meat and potatoes along with the psilocybin."
