I really can't stop litening to this album right now. This is not like anything I've heard before. It seems to be a bit of a concept album.
The first six tracks really comprise two songs, developing cyclical, hypnotic riffs, which never slow down for a second. It's brutal and relentless, and I think quite genius.
I don't understand what Mind's Mirrors is all about. It completely destroys the pace established until then. It picks up again at In Death - Is Life though, one of the best tracks. The rest of the album chugs along, with a few more quiet sections, until the awesomeness of the main riff of Sum, which I just can't get out of my head, but that tails off into a long passage of noodling, which I guess is supposed to sooth your mind after the skull-(.....) it has just endured.
This album is mainly about developing themes. Break beats drive the music along and the hypnotic riffs grab you and won't let go. There isn't a lot of mid-range guitar noise here, mostly bass and treble. Time signatures are all over the place and very freestyle and inventive, but strangely funky. The vocals are pretty ethereal and distorted, sometimes sounding a little industrial.
Meshuggah, "crazy" in Yiddish, really live upto their name here.
