The Call of the Didjeridu

The DIDJERIDU… Didjeriwhat ? Where does it come from ? The Aborigines… who are they ? That's not a musical instrument… is it ? How does it work ? Where can I put my hands on one ? Is it possible to craft it myself ? How do you breath in and out at the same time ? And how do you produce all these strange noises simultaneously ? Didier heard the Call of the Didjeridu. Along with his cunning dog Ridoo, he will find the answers to all those questions through his different encounters.
