I received a pre-release copy of some tracks by a Seattle-based duo by the name of The Solaris Project recently. They create long, interesting drones with guitar and koto. The tracks were all recorded live, with minimal post-production fussing with. The result is some really top-rate ambient music.
No news just yet on when they'll have tracks available for purchase or download, but in the meantime head over to their MySpace profile where you can stream 3 of tracks from the disc I received. I'm looking forward to hearing more from these guys.
