Whilst I have the chance, can I pick your brains about "Gorguts" Walk? Do they employ similar growly vocals? I've heard them touted highly by some and wanted your thoughts.
Gorguts use a lot of unorthodox elements in their metal. Their song structures are always weird and hard to pick up on and remember. The drumming is very technical, and they don't overuse the double bass. I prefer Deeds of Flesh (they're easier to listen to), but Gorguts is still a very great death metal band. I recommend their album Obscura to start out with. It is EXTREMELY dissonant, even by death metal standards, but it's musically brilliant.
And yes, Gorguts use the death voice, but it's not as deep as many other bands, but still very grating. If you want death metal without the death voice, you'll have to look at either melodic death (uses it occasionally) or old school 80's death metal. You should start with that stuff first.
