With Polarity, the new full-length album from technical death metal wizards Decrepit Birth, let’s get the following out of the way immediately: the musicianship and sheer technical prowess displayed by the musicians in Decrepit Birth is hard to top, even in a genre known for the technical skills of the top acts. Unbelievably fluid guitar and bass work is backed up by exceptionally precise drumming, covering a wide range of tempos, throughout the course of the entire album. In short, Polarity is a tour de force of precise musicianship that, to the ears of this non-musician, ranks with the best performed in metal.
