Great idea to experiment with different soundscapes. The build-up in the beginning is quite nice. Until about 1:00, the piece seems to be a meditation on a short phrase. Then, it seems to me like the material changes (until one is again reminded of the first minute), but little is done with this contrast. - Either a bit more development or a tack more minimalism could improve the piece so that it doesn’t remind anyone of a background track waiting in vain for the main voices ;-)
