CIRCLE

Circle is an a very good ambient album, and with the exception of a few 'active' tracks, excellent for falling asleep. I'd put it in the same general territory (though not nearly as high up) as Wendy Carlos' Sonic Seasonings, or some of Eno's Ambient albums.

Definitely not prog music, unless you want to consider this in an "ambient progressive" category.

To me, this is headphone music, and not something I could listen to over speakers. And most definitely not while driving.

One of the things that's worth listening for is the way that Watkins blends together the nature sounds in a decidedly non-natural way, mixing different insects and animals for a non-nature effect.
