San Francisco’s Kowloon Walled City and Brooklyn’s Batillus are respectively responsible for two of the finest sludge albums of the last two years (KWC’s excellent Container Ships made our list of 2012’s best metal albums). Now the two bands are teaming on a split EP for which they swap singers and cover latter-day songs by a pair of industrial heavyweights (and obvious influences), Godflesh and Ministry. We’ve got the A-side for you to check out today: “Anthem,” from Godflesh’s 2001 album, Hymns, performed by Kowloon Walled City with Batillus’s Fade Kainer on vocals. (The B-side is Ministry’s “Lava,” from 1996’s Filth Pig, played by Batillus with vocals from Scott Evans of KWC.) The pacing and instrumental tones stay true to the original, though it’s heavier and rougher; where Godflesh frontman Justin Broadrick cooed his vocal, Kainer barks and snarls. Check it out.

The “Anthem”/”Lava” split is out 12/10 via Brutal Panda.
