your perspective is rather one dimensional, and seems not entirely well intentioned.
The music you're posting may well be of great interest but this,is a negative context to share it in.
apologize for harsh language. I'm just sick of the conceit of modern culture, which thinks that it is the most advanced, and does not acknowledge traditions it comes from. (and of the west as well).
all of the formal "innovations" and ideas of modern music can be found in music from Madagascar, Indonesia, India, etc., etc.
as Turtles noted, that Madagascar track sounds like something Vilalobos would do (wishes that he CAN do).
Georgi Ligetti's ground breaking formal innovations such as "micro-polyphony" was derived from African music. and a lot of his melodic invention came from Hungarian folk music.
many, many other examples.
what I'm saying is that things are not separate as people think they are. continuum, rhizome, whatever. everything is connected and you find the new in the old, and the old in the new.
that's all.
