If any album embodies the true spirit of Thrash Metal, besides "Reign In Blood", it would have to be "The Legacy". This will probably be forever hailed as TESTAMENT's finest effort, the band seems to be doomed to have every album compared to this, despite the fact that they've evolved with the times while sticking to their roots quite well. Still, many view this as the band's "end all be all" of their discography, and while I think they produced several excellent albums throughout their still-thriving career, this one remains their hands-down best. You just cannot hope to compete with "The Legacy".
"Over The Wall" is like a private lesson in classic Heavy Metal-riffery, opening with perhaps TESTAMENT's heaviest riff ever written! Choppy, quick, perfectly punctuated with an accompanying harmony, striking like a venomous serpent. This begins the tidal wave of molten Metal to follow for the next 38 minutes, never getting stagnant, each song just as Thrash-o-riffic as the next. Exploding onto the Metal-scene with this album was also one Alex Skolnick, who's dizzying guitar-gymnastics and melodic wizardry would make him the legend he still is to this day. It was definitely Skolnick's lead-abilities which helped make TESTAMENT such a defining force in Thrash Metal, as each song contains a healthy dose of Skol-itics (!) for all shredders to sink their teeth into.
This goes without saying that all nine compositions are neck-snapping cuts of choice Metal-tenderloin. From the razor-sharp riffs of "The Haunting" to the dark melodies of "Burnt Offerings" and "Alone In The Dark", down to the closing Thrasher "Apocalyptic City" (containing, in my opinion, Skolnick's finest solo to date), this album exudes only the purest essence of what Thrash Metal is, helping to singlehandedly immortalize the entire genre as we know it!
A truly hallowed chapter in the Book of Thrash...
