The biggest improvement comes in the vocal department. Frontman Mark Hunter has broadened his range considerably; his hoarse, acidic delivery is laid over dark, Layne Staley-like harmonies and a deep, death-metal growl. Guitarist Rob Arnold pulls off one dive-bombing solo after another, and the dexterous drumming of rubber-armed Andols Herrick continues to amaze. Their combined musicianship elevates such songs as the dirty dirge "Crawl," the soaring first single "Down Again," and the shockingly savage "Pure Hatred" into instant anthems. The Impossibility of Reason is a true Cleveland-metal classic.
