Mark, they're a very unique band, so if you havent heard them be prepared for some weirdness. I'd expect an initial reaction to be 'what the $% is that?'.
All of the music theory dissection details how they go about creating a disorienting and bizarre, eliptical vibe to their sound. I think they're the most original band in decades. (And they do what I was on about in the other thread really well; their music is technical as $%, but its that way for a real musical reason other than to just be technical; to make this otherworldy sound thats heavy and percussive, rhythmically intense, but confusing and $%ed up - its extremely heavy music with the same tendency to float along and refuse to pin down that jazz has)
Start with destroy erase improve or obzen. They arent very accessible, but those are probably the easiest to get into. Catch 33, chaosphere and nothing are the most byzantine. Catch 33 is an album written as a single song that was broken up later.
And, no, they are nothing like KSE. Dont get me wrong, KSE are alight (but no more than that), they are just very dissimilar.
