International audience The flourishing sector of the popular music of Madagascar would be based on quasi occult structures of production initially organized by family networks gathered in and around the markets, contexts of interculturality, which are traditionally opened to circulation of cultural informations. The « defense of a cultural authenticity » does not seem to be the organizing concept of these networks whose concern, like everywhere else, is the safeguard and the extension of a public. Thus, with regard to the « great groups » whose notoriety and statistics of « sale » are known, it would be the search for originality, the creativity thus, – opposite competition – and not of « authenticity » which would balance a too strong adequacy with the requirements of the « market ».
