I found this on gonna get sued which is a very awesome blog run by the one of the dudes from Book Of Caverns. They are a rather obscure mathy, post rocky screamo band from Vancouver. They have one of the members of Wrought: Ironsmile who played a lo fi emocore.
The post rock on this album is mixed with some math rock so I can actually get through the songs. A lot of them are slow burning and never necessarily boil over but they still manage to kick ass.
Also very unknown, more people need to know this. More for the math people than screamo people probably
