After dropping their groundbreaking debut album on an unsuspecting world in '89, just two years later they unleashed a new level of aggressiveness and creativity that no one could have expected. Somehow effectively blending the use of violins / violas, a female opera singer, and thrash metal, Believer stretched the boundaries of metal beyond the normal limitations of the genre. By maintaining the highly technical aspect of their progressive speed metal they thrilled metal fans in both the mainstream and Christian markets. Sanity Obscure would go on to become a standard "must have" album for fans of thrash metal in the vein of Slayer, Tourniquet, Kreator, Exodus, and early Living Sacrifice. Fast and furious, the dissonant and growling aural mayhem ensured Sanity Obscure was one of those albums that grabbed the hearts and souls of even casual metalheads. To say that this 1991 album has stood the test of time is a grand understatement. The release of this album opened the doors for the band to play mainstream venues with bands like Bolt Thrower, as well as have their albums widely distributed in mainstream markets. Even in the year 2004, Heaven's Metal Magazine reviewed this reissue and describes the Sanity as "...one of the classics of yesteryear...highly technical thrash with addicting, hypnotic riffs, and aggressive drumming that pound relentlessly at your skull."
