Just discovered Voivod and my brain hasn't been the same since

I've been going down a rabbit hole of technical/progressive thrash metal lately, and somehow Voivod had completely flown under my radar until now.

I started with Nothingface. It's like someone took prog rock, psychedelia and thrash metal and threw it all into a blender set to "alien". The dissonance, the atmosphere, the way every instrument feels like it's playing in its own weird orbit while still making perfect sense together. Then I went back to Dimension Hatröss and if anything it hit even harder.

I'm amazed this band isn't mentioned in the same breath as the genre's greats every single time.

Now I'm looking for recommendations. If you love this era of Voivod, what else should I be listening to? I'm particularly drawn to:

- The avant-garde/dissonant approach to riffs

- The sci-fi and existential themes

- The progressive song structures that don't follow conventional patterns
