Have you heard Steve Roach?
Amazing and productive sound designer/producer/composer making "soundworlds" for almost 30 years now I think. His material is real vibrant and organic for electronic music. He's very connected to nature and you can sense it in his work. Look at this dude's discography. He's had like 5-10 releases a year for at least the last decade.
Some of it pure synths.......

Sometimes he uses ancient percussion and various ethnic instruments.

He also makes these albums that are like one 70 something minute track of really complex and spacious, evolving drones.

All very spiritual and trance like. Most of it cuts right into your brain's primordial pleasure centers but can also be kind of dark and alienating at times. It's absolutely THE music to experience when walking the forests or deserts alone at night on a shroom fueled, soul searching, peyote binge. Or just winding down the final moments of an evening while it lulls you into the dream state (A daily ritual for me. Even with my battery powered ipod speakers in a hotel room or a tent.)
