Excellent proposals from @Amenbreak (with the Monotrail Tech Talk video) and @Lugia (with the technical suggestions). For my part: E352 Cloud Terrarium, Nebulae and Morphagene are some of my favourite modular sound sources for that musical genre.

But I think that with various means (and sometimes little means) we can obtain interesting things, because it's actually and mostly a question of mindset when creating and listening.

We can refer here to the music of bagpipes (wind sounds), Ravi Shankar (string sounds), and the historical works of La Monte Young (‘Trio for Strings’) who is one of Eno's references.
