Before the album's release Metal Blade Records had this to say: Led by the inimitable Chris Barnes, possessor of one of the most dominant and instantly recognizable voices of the death metal genre, Undead offers up an overhauled lineup. Now featuring Barnes alongside new guitarist Rob Arnold (ex-Chimaira), longtime guitarist Steve Swanson, and drummer Kevin Talley, whose history blasting for Dying Fetus, Misery Index, and Chimaira speaks for itself, Six Feet Under 2012 finds the band reinvigorated and churning out some of the most visceral, in-your-face, and downright horrifying tunes in their renowned discography of brutality both, lyrically and musically.
Comments vocalist/death metal ambassador Chris Barnes of the recording: "I'm in pretty much the best head space I've been in since myself and [former guitarist] Allen West started this band in 1993. I'm super excited about the new record. It's a rejuvenation; it's a rebirth of Six Feet Under, and fans will definitely latch on to my excitement and how focused I am in the lyrics I've written… The hypocrisies of daily life, things that affect us that spawn aggression, loneliness, sadness, there's a lot of emotions going on across the record, and I guess that the dark horror that humans cause is my niche."
Called "the best thing SFU have recorded since Maximum Violence," in a 8/10 review by Decibel magazine. Terrorizer magazine wrote that, "Ugly riffs slip and slide amidst the primordial ooze summoned forth by Chris' guttural incantations, and the drums flail in the background like some tentacle monstrosity from beyond; this is truly an unearthly noise and glorious in its heaving absurdity."
