Merzbow is noise music. While this may seem like an overstatement, Masami Akita is the forebear of the genre itself not to mention the most well known name in said genre. So i would have a hard time believing anyone involved in noise in even the most perfunctory way would pass up the opportunity to work on a project with him.
So i assume when former Sutekh Hexen members Scott Miller and Lee Camfield received that call they couldn't help but say yes. While Merzbow is not new to collaborations or trying different things this is something different. While Merzbow lays a bed of sound that makes for the more recognizable aspect of the recording Miller and Camfield regularly act as a melodic foil of sorts adding a more organic side to the recordings.
This gives the listener a nice point - counterpoint feel for most of the record allowing for both the harsh cold of Merzbow and a more humane and familiar feel on the other side.
this is something different to most but if you are interested or already a merzbow fan you could do much worse than make this your entry point.
