A Decade In The Grave is a box set (4 CDs + 1 DVD) by death metal band Six Feet Under. It was released in 2005 on Metal Blade Records. Ten years after the formation of Six Feet Under, Metal Blade celebrated the band's longevity with A Decade in the Grave, a five-disc box set (four audio CDs plus a DVD). The first two discs is SFU's best-of, disc three contains rare demos as well as live performances, while the fourth disc contains demos and rehearsal material by Leviathan (the band Barnes sang for before Cannibal Corpse or SFU). The DVD offers a blend of videos and live performances. The box set also includes 4 new songs, "Dead and Buried (Living Life in the Grave)", "From Flesh Bone", "A Knife Fight to the Death", and "Burned at the Stake", the latter 3 being previously unreleased, and the former being recorded for the album.
