Cause for Effect is one of the most unique bands I'm aware of. I ran into them by chance at a gig a couple of years ago, and that was one of the most amusing half hours I can remember having in a rock club.
Bass, drums, low grunts, that's all. This group runs rings around time signatures and conventional structures, conventional sound, conventional anything. A truly special blend of jazz, groovy funk and blast-beating extreme metal. The average length of these tracks is under one minute, and one is also the number of different notes used by the vocalist over the course of the entire album. Half an hour of this stuff is the extreme that one can handle in one sitting, but quite surprisingly it's a relatively easy and enjoyable swallow.
This is definitely collectors/fans stuff, and an excellent addition to any such collection. Three stars is a fine compromise between them, and it ultimately reflects very well the level of enjoyment I get from this album. To pay tribute to this music I've kept this the shortest review I've ever written on this site.
