Thanks, I will check in time, for sure

I am just preparing to go to a workshop about asian intruments (Sheng amongst it, actually) in out Academy of Arts, followed by a fine concert with this new group.
Yes, I love to listen to that Touareg group as well, and did ever so often. The advert is on for quite a while already.
As for the European regions, the funny thing is, the Jodel-Techniques are not far from the throatsinging ones, and in some near asian regions, they also have some according jodel parts in their songs, often wedding songs.
All these techniques must also have to do with a kind of long distance communication (yes, the overtone and jews harp ones too), it probably has to do with the frequencies. . .like those of whales for instance.
However, it is based on ancient shepherd songs and how also animals react to them, plus certain shamanistic sounds, that are still alive in many parts of the world, not just drummming, but also via voice.
If you have ever tried such throatsingings, or jews harps yourself, you may know, how it effects you immediately, if done the right way. It creates a kind of natural high and tickles the top of your headskin, electrifies you, with other words.
No wonder, animals for example give more milk for instance or are easier to handle then, mating offers are more successfull etc. etc.
Not to speak about the colours and pictures it evokes in Synaesthetes, a natural form of reaction, that we often lost, but can gain again.
And pleasure (about all this, not just the syn. ones) is a key for all parts of the world.
If these sounds grow again, it might also train/wake up oldest skills, understandings.
The Japanese seem to be right into this as well, they also found some relations via their Ainus, for example.
As much as any didgeridoo adds to this etc. etc.
The musical move is by far not only into the artificial sounds, but also into the old knowledges, plus new mixes of both. Highly interesting, I think.
