good link! I like the samples up there too sounds like you're already getting some good recordings.
The one thing I couldn't find was what kind of pre-amps you're using though. I'm geeky I know, but I'm a fan of outboard as well as software toys!
The good thing about world music and meditating stuff from a production point of view is that you can go pretty wild in the experimental side of things.
From the recording point of view, you can mic performances traditionally, you know, pointing mics at bridges of Cellos and guitars, pianos being mic'd from 2 meters away at head height in a stereo pair.... but you can also play with contact or boundary microphones put on the floor, or on the body of the instrument itself for an 'inside' sound.
You can also get very experimental with re-amping your recordings and aiming the amps at gongs or piano strings and get all kinds of shimmering reverbs. Layer that as a bed under your recordings and you have something unearthly, but musically sympathetic.
There was a group called Ravi Harris and the prophets and Ravi himself was a sitar man but he did indian funk versions of lots of James Brown stuff, amongst other things. I wouldn't say he was extremely experimental with the sounds but the vibe of the sound he got was very good.
There's another indian chap who's name escapes me right now, but he did all kinds of cool stuff.... I'll dig it out and re-post with his name.
Whilst I remember, the results you get from using two mics can change things quite a bit too depending on where you position them. Taking advantage of the phase relationships between the two is what it's all about!
If you can give examples of what you're trying to achieve I can hunt around a bit more for you if you like?
