CUT RIBBON by Steven Wilson
pretty badass as I remember it. It being the original demo that was on his myspace, that was at least inquired, if not mentioned to be part of the project he was to make with Mikael Akerfeldt. That project, now being Storm Corrosion. But I follow why it (likely) will not.
It's probably best suited for one of his solo records or Porcupine Tree.
