"Negative Infinity" is a sort of return-to-form in a regard, featuring 6 tightly scripted doses of what they call "Brutal Prog" - the tag Weasel coined in the early 2000s to describe an elite breed of intense, complex bands who emphasised harshness and intensity over the typical prog-rock flutes and fairies positivity. This is prog for the Aocalypse, not your uncle.
