"The Luster of Pandemonium" is definitely a difficult and demanding listen, but if the listener puts enough time and effort into it, I think he/she will find that the spirit it conveys is more powerful than just about anything to come out of death metal since Gorguts' "Obscura."
In fact, no other death metal album released post-2000 has spent as much time in my CD players as "Luster..." has, and at current, its playing time even rivals that of any number of classics on caliber with those that I mentioned in my first post.
Anyway, this thread is about Portal, not Crimson Massacre, so if you'd like to discuss "Luster...," please do so in another thread. Having spent many, many hours analyzing the album, I am more than happy to go into greater detail as to why I hold it in such a high regard.
