About an hour ago, and almost exactly one year after the release of Surgical Steel, Carcass posted the image you see above on their Facebook page, with no further explanation other than the words “Sshhhhhh! Mum’s the word!” (as if). But it appears to be an announcement of a forthcoming vinyl EP to be released by Nuclear Blast on November 11, 2014, entitled Surgical Remission/Surplus Steel.
If I’m interpreting the flyer correctly, the release will include five tracks. “A Wraith In the Apparatus” appeared as a bonus track on the Japanese edition of Surgical Steel; “Intensive Battery Brooding” was the B-side on a 7″ vinyl single for “Captive Bolt Pistol” and also appeared as a Japanese bonus track on Surgical Steel; “Zochrot” was a single recorded during the Surgical Steel sessions that appeared as a Flexi-disc in the October 2013 issue of Decibel magazine; I’m pretty sure “Livestock Marketplace” was another song recorded during the Surgical Steel sessions but so far as I know it hasn’t been previously released; and “1985 (Reprise)” may be some sort of re-working of Surgical Steel’s first track.
That’s what I know or have discovered from my researches.
