Please Help Identify Video Music

My first guess was something like Steve Roach and Robert Rich, from TAS Hearts of Space, but I have that.

I emailed the OP, but he said it was a random pick from YouTube.

The music is very haunting and effective, I'd love to have it.

Sounds an awful lot like Maps and Diagrams but cannot place the song or album. Just more of a guess from the texture and instruments. Field Rotation comes to mind as well.

A side note, if you are into ambient/drone, explore Tim Hecker (if you have not already). Most notably his last, Ravedeath 1972 and the Dropped Piano's EP. One of my favorite albums of the year.
