Continuing to expand upon his over the top performance from the last album, Billy demonstrates an aggressive versatility that is unheard of in this genre, as his voice fluctuates from angry to more angry to downright snarling. Demonic suffered because it lacked vision, however, The Gathering is pure focused aggression, which is why it is such a monumental release for Testament. Songs like "Eyes of Wrath," "True Believer," and "Careful What You Wish For" demonstrate a catchy, uncanny songwriting ability previously unseen in this band. While "Legions of the Dead" is bar none the heaviest song Testament has ever written. Nevertheless, it is "Riding the Snake" that takes the cake on this album. Here the entire band pulls out their finest arsenal. Lombardo pounds away at his kit with equal precision and intensity, while Murphy and Peterson's guitar interplay is playful and masterful. The real gem is DiGiorgio's four-stringed feats, which consist of a Tony Choy-esque solo that is nothing short of extraordinary.
