around my area you play the vocal part of this the wig gets flipped to next dimensions.
new age stuff has a lot of reliance of vocals and airy vocals.
now. this is my area i was really into 3 or 4 years ago. Ethiopian jazz. they have a various different languages in the region. using that and due to a heavy but still pretty distant colonial influences you get some great jazz phrases where as other places have a sort of 'American jazz with native language on top' i.e. japan or china. Ethiopia has it's own style and culture. to mke it completly unique for such a relatively small region. it's unlike many other musical forms. using that gemination and augmented vocals.
