Writing a follow up to what some would consider one of the best metalcore releases ever is no small task. Keeping things fresh in certain genres is becoming harder and harder with an ever-growing pool of bands, but Alabama-based Erra have managed. Augment, couldn't be more aptly titled—every element of the band's sound has been refined to near perfection. The already excellent guitar work is taken to another level with more solos crafted with utmost attention and phrasing achieve what many bands stumble. Both clean and harsh vocals sound better than ever, with the cleans sounding more comfortably performed and the harsh parts cutting like a chainsaw.
