i quite dig this track, there are very subtle changes which are interesting amid the repitition. i'm a big fan of ambient and microsound stuff, so this is cool for me, and it's by far the most minimal, ambient track autechre have ever released. i look at this whole quadrange release as a bit of an experiment, what with all the versions and the way it was released. and this final track is the culmunation of the experiment.
also, makes nice reading music! :-)
