I'm confident that I can successfully defend the case that this is the most influential metal album of all time. There were many albums that broke some boundaries of experimentation and created a whole new quality in music either by combining some elements never heard together before or pushing some of the limits further, but none like this one.

While most death metal bands were busy exploring speed, technique and virtuosity; heaviness of the sound; extremities of vocals; progressive rock arrangements; jazz theory composition or even improvisation, Gorguts went in a direction of avant-garde contemporary classical music with all its atonality and dissonance experimentation. You need a well-trained ear to even hear music when you play this album for the first time. And so was the experience of the average metal consumer back then. This was so ahead of its time that it remained a niche thing for weirdo geeks for a decade or more. Today we have a whole genre called dissonant death metal.

Here are my favourite albums of that genre:

1) Ingurgitating Oblivion - Vision Wallows in Symphonies of Light
2) Aseitas - False Peace
3) Anachronism - Meanders
4) Gorguts - Obscura
5) Gorguts - Colored Sands
6) Ad Nauseam - Imperative Imperceptible Impulse
7) Ad Nauseam - Nihil quam vacuitas ordinatum est
8) Abyssal - Antikatastaseis
9) Defacement - Defacement
10) Nightmarer - Deformity Adrift
11) Artificial Brain - Labyrinth Constellation
12) Artificial Brain - Artificial Brain
13) Convulsing - Grievous
14) Pyrrhon - What Passes for Survival
15) Imperial Triumphant - Goldstar

I need to stop somewhere, there are so many...

I don't like Ulcerate, there, I've said it.
