Sludgey Doom with strong elements of Stoner Rock, or vice versa. The vocals are definitely more Fu Manchu than Khanate, the chords and progressions more like very old Swans or new Throneless. Heavy stuff for sure.

Debut album from a group of old men, including Tim Bagshaw and Mark Greening of Electric Wizard, and singer Lee Dorrian ex-Cathedral and Napalm Death. While hardcore and speed metal are perhaps a young man’s game, With the Dead prove that doom only improves with age. It’s as if all the happiness, joy, and optimism has been drained out of all three of them, and they’re just left with a miserable acquiescence to the rottenness of the world. The sound is super heavy, simple, plodding, a constant enveloping mud bath. Terrific!

1) (7:43) big epic one, some vocal harmonies in the chorus give a slightly slicker feel but anything but cheesy when many bands do it 2)* (8:17) strange brief sample in start, then a nice pounding stoney chord progression 3) (6:26) big slow riffage with doubled up vocals that are more stoner rock than doom metal 4)* (8:50) riff based slow doom 5)* (10:12) low spooky atmospheric dark plod, builds glacially, a dark poem appears after 3 minutes, then in about 5.5 minutes the expected slow doom crashing appears 6) (6:39) big huge doom out the gate 7)* (17:37) begins spooky slow industrial noise, then a soul crushing blackness ensues, slow glacial plod, toward the end a bizarre electronic sound just creates insanity, therapeutic for sure
