Ever since last wednesday when I got the fantastic Mystifier 1989-1993 Baphometic Goat Worship boxset that was just put by NWN, I have been listening to nothing but Mystifier, and this demo in particular.
Tormenting the Holy Trinity is my second favorite Mystifier recording (Göetia being the first), and the reasons why are plain and simple. This demo definitely shows them at their rawest and most bestial stage and is pretty much the epitome of all things unholy and evil. Everything is extremely fast without ever getting old, and even at the first stage of their progression to the masterpieces that would follow for the next 4 years, they still had song writing skills that were above a lot of other black/death metal contemperaries, as well as more interesting lyrics then the average band of that era. But of course the lyrics are nothing compared to what was to follow on later releases, where they began to discuss things such as the occult and dark literature.
Highly fucking recommended, along with the rest of the boxset. Download and buy!
