Jacob Newman and Devin Underwood - The Vivid Unmapped
A 2011 release from DataObscura. I recall Joe R. and others singing the praises of this album a while back. I picked up the digital version on Bandcamp last week and have been enjoying it immensely. It has a little bit of everything: a classic ambient feel with warm, drifting synth notes and a bit of an experimental angle, with found founds, interesting sonic manipulations, etc. The atmosphere is great--not too dark, not too fluffy, and somewhat mysterious.
I knew you'd like it, Chris. And your description is spot on. Beautiful stuff! Some tracks have an amazing sense of distance, as though you're hearing sounds of life and nature from miles away.
