Anything akin to tech death but not as tech.. something like Obscura with a little less wank.
If you haven't tried Hypocrisy... their newer songs have a tech touch.You can also try Atheist...but I doubt you never heard about them.
Hmmmm, I dig. Yeah, I have heard of Atheist. I don't think anybody I know hasn't, unless they live under a rock. Anything more like this you might have? Doesn't have to be exactly to what I specified. Anything prog/tech death oriented is fine.
