I've been a fan ever since I first heard the greatness of Constellations, and then picked up Messengers. Leveler was just alright for me, but I'm looking forward to hearing this record, I'm sure it will be great.
It is rare for a straight-up metalcore album to be good these days. August Burns Red is really the last of these groups I think can still bring it (now that As I Lay Dying is dead). This is their most melodic album yet, too.
