For the last five or so years, Virginia's Lamb of God have been leaders in the American metal revival and its rise in mainstream popularity. They deserve the attention. On their fourth studio album, the band formerly known as Burn the Priest (think these guys have a problem with organized religion?) don't veer off in new directions so much as they simply perfect and further hone their existing sound. Opener Walk With Me In Hell has 2006 arena-metal anthem written all over it, while Blacken The Cursed Sun encapsulates all facets of the band's fierce appeal, including singer Randy Blythe's ridiculously good guttural offerings and healthy doses of chugging double-bass grooves.
