That's a fantastic album! I don't really have a favorite ABR album, because they top each previous album and grow constantly. They are, in my opinion, one of the most interesting bands out there.
They take the common misconception of Metalcore being all about breakdowns and chugga-chuggas and smash it to pieces with their masterful instrumentation.
If you can't tell...I love ABR. Still haven't had a chance to see them yet though...
