I found a connection with Engram almost instantly because of its spoken introduction. I see that statement as the reason to come back after 14 years and make an album like Engram. Having read Nuclear Holocausto's interview with Terrorizer, especially the snippet posted on this forum, this seems justified.
At some point in the past, writing music was limited to the few people who were brilliant enough to compose and express themselves through it. Once music became a commodity, it ceased to be a form of expression, because writing "music" became as simple as following the rules of what "sounds good" and what doesn't. Today the brilliant people who can express themselves through music are lost within masses of those who don't even know that music is a form of expression. Black metal died like this and perhaps as an act of contempt toward the current situation, Nuclear Holocausto decided to return with Engram and perhaps his introductory statement means just that.
In my view, the album is a complete success, because it is a structural masterpiece - perfectly clear and engaging in its progressions - with a natural beginning, middle and end. A lot has been said about the use of layering and rightfully so, because the progressions arise from layers that are both simultaneous and sequential - the latter meaning that one phrase comes over the previous. Without that, the album would be stuck and pointless.
