Thanks Richard. I do have Stearns' M'Ocean, which I enjoyed, but haven't listened to in a while. Perhaps it's time to give it a spin.
Robert mentioned Dweller at the Threshold (why do I think of Piper at the Gates of Dawn when I see that?) and I checked out their site. They've got a good MP3 demo that I liked a lot.
Haven't been able to dig up much on Pan Sonic or Plaid. It seems I recall these being more toward the Techno vein.
Some other thoughts -
Kitaro. Have a few of his. Not a huge fan, but I enjoy from time to time. Can get repetitive IMO. I have a taped copy of what I believe is his best (or at least my fave) called Ten Kai. It was very obscure relative to his other titles when I got it about 15 years ago. Have never come across the CD, but would put that at the top of the heap of his stuff.
Also thinking about some other stuff -
Eno/Byrne - My Life In the Bush of Ghosts and Byrne's The Catherine Wheel, though I don't think these fall in this category. Just interesting music.
