The two-year long-wait is over, and those Mastodon fans encouraged but leery of the slicker production of Leviathan over Remission will be even more bemused, or downright bewildered, by Blood Mountain, the band's first foray into major-label territory since signing with Warner Brothers' Reprise imprint (after all, this was the label conceded to Frank Sinatra as his own when he threatened to leave it). Blood Mountain is everything fans both hoped for and feared. Mastodon has dug even deeper in its foray into prog metal, but without losing an ounce of their power, literacy, or willingness to indulge in hardcore punk, doom, and death metal. Like Leviathan, Blood Mountain is both melodic and downright raging in places. Matt Bayles is in the producer's chair once more and he's encouraged this Georgia quartet -- Bränn Dailor (drums), Brent Hinds (guitar and vocals), Bill Kelliher (guitar and vocals), and Troy Sanders (bass and vocals) -- to take it to the limit. And they have. Blood Mountain indulges and goes deep into the territory of prog metal beats and quests and spiritual revelations that have less to do with Tolkein-ism and more to do with Conan-ism. There are utterly beautiful melodic passages woven into the heaviness that are reminiscent of Thin Lizzy's dual guitar lyricism -- and the band has confessed to digging Phil Lynott and company. The vocals -- with guest spots from Neurosis' Scott Kelly, the Mars Volta's Cedric Bixler-Zavala, and Queens of the Stone Age's Josh Homme -- are mixed way upfront and the number of sheer stylistic changes is dizzying.
