Over 2.5 hours of ambiance and mood. I haven't gotten to listen to it in full yet. Beautifully evocative virtual soundscapes, subdued one minute, provocatively intrusive the next. Great on a night drive, or working music, could even meditate to it (my yogi gf loved it as drive ambience) My first Disasterpeace experience and I don't really listen to this sort of music and I find myself glued. Favorite keeps changing.
