I don't remember how/where I first found them.  I'll admit that the only reason I started listening to them was because I'm a huge Frank Herbet fan.  Regardless, they are a good band.  I guess they are now considered metalcore.  I've seen someone say melodic deathcore.  That kinda fits too.  They have a heavy, thick, aggressive sound.  The vocals are growly/shouty.  I need to write out a better description.
