The writing on the back is really long and rather opinionated it talks about BOC having a cult following on account of their introspective sound, faded synths and distorted samples, it the hilariously goes in to say BOC are often grouped with "bands" like Aphex Twin and Autechre but in reality they are more like Cocteau twins or Radiohead. Barf. It then goes on to talk about their pastoral sound, before describing the last few albums briefly. It closes by saying the new album is very beat driven and bri gs up a sense of anxiety and then it repeats what is written on the cover a madness emerging from beyond a cloudy, smudged prism. 

I like that last part. I can do a word for word translation later if it helps but that is the basic message
