Formed in 2004, New Zealand''s Diocletian, Darkness Swallows All is a special four-song EP of all previously unreleased material, recorded around the time of massively influential Doom Cult debut full-length. The first two tracks, feature alternate vocals by guitarist L.M. and are equally devastating as their original versions, a cover of Bathory''s Possessed, with vocals by Black Witchery''s Impurath, concluding the EP is Oath to Ruin, an otherwise-unearthed treasure.
