I recommend "The Mystical Gate of Reincarnation" by Kataklysm. They got more and more boring as they went on after that release, though Sorcery is decent from what I've heard.
"Unorthodox" is Edge of Sanity's best work, it's interesting scan-death.
Falconsbane's review of the Kataklysm on M-A, which is accurate:
"Brutal death metal has never been a creatively fertile field. For the most part, it has been an artistic charnel house of bad ideas, bad cover art and awful jock rock. Kataklysm's debut mcd is an exception.
"The Mystical Gate of Reincarnation" significantly both from its brevity (21 minutes) and a wonderfully organic, bass soaked mix. The core of this work (like so much of the best death metal) is the struggle between alienation from a meaningless universe and the endless possibilities open to those with the courage to impose a new order in the midst of Chaos. Kataklysm display an easy fluency both in the language of violence and the symbolic world of the Will, embracing the paradox inherent in their struggle through the juxtaposition of relentlessly punishing rhythms and calculatedly articulate structures, pulverizing, scraping riffs and the roaring silence of atmospheric melodies. The result is an album seething with passion and rage, yet intelligently reflective. Highly recommended."
