Much more aggressive than redundant Slam Death, way more direct and uncompromising than boring Tech Death and without an ounce of the regressive nostalgia of the "Old-School", Ad Patres creates the perfect balance between musicianship and heaviness, topping it with lyrics delving deep into the human mind's darkest recesses. As such, "A Brief Introduction to Human Experiments" makes a somber parallel between psychology and religion, blurring the thin line between those two mind-manipulation "schools" clearly showing psychology is the new Christianity and psychanalysts the new inquisitors of the "right way of thinking" through a relentless, pure Death Metal, album that dissects both (religion and psychology), like twisting the brain in a split wide open skull. Not recommended for the faint of heart, this is French Haute Suture.
