Really Heavy Tech/Math Metal

Math metal isn't metalcore at all, it's just a form of progressive metal with weird time signatures. It's supposed to sound really chaotic but still have form. That's my understanding of it.
 
Textures
Ion Dissonance
Wicked Innocence

They are the only ones mentioned in this thread with any math aspect to them. Tech and math are obviously different.
 
I have the perfect band for you, it has everything you need. But damn, I can't remember the name... Oh well, cya :)
