Mick Harris is celebrated for jackhammering the apocalypse at 200 bpm on a trapkit for grindcore avatars Napalm Death. In his incarnation as Scorn, he settles down to watch the nuclear winter set in. With Plan B, Harris continues to explore brooding dub atmospherics with ghostlike piano melodies and DSP noises that roil in psychosomatic flashbacks over hip-hop beats that land like fists. Unfortunately, he clings to this formula too tightly, where the majority of the album seems to be remixes of the same track. This problem is heightened by some plodding drum machine rhythms. Harris thankfully breaks that monotony with the self-immolating polyrhythms that shatter like storefronts in a street riot in “Sleep When Home” and “The Snow Hill.”
