I'm glad you like it :). I think ambience and soundscapes should still have interesting musical elements. If it only works as background noise, then I get bored by it.

I've also listened to Isis quite a lot, mostly "Oceanic", which is great. There is a pretty good remix album of "Oceanic" that opens with a remix by Fennesz.

Let me just throw a few more out there:
