"Between 2003 and 2006, Bastien Lagatta, musician and ethnomusicologist, undertook musical researches among the agro-pastoral societies of the Omo valley, thanks to the support of the CNRS, the Ministry of Foreign Affairs and the UNESCO. For months, he has shared the everyday life of the semi-nomads tribes Nyangatom, Mursi and Bodi, and has taken up the study of their musical repertories. The trek, of several hundred kilometres along the Omo river, in such an amazing natural environment, led him to the heart of Humanity with its peculiar mores, customs and habits. Greatly endearing, these men and women live in a world whose balance is precarious. These recordings reveal the importance of this patrimonial, cultural and artistic heritage."
