After the postcolonial socio-cultural upheaval in Africa, the griot caste gradually became a caste of professional musicians. Ganda is an exception: he has been able to remain in the pure tradition of the griots by perpetuating the transmission of the values ​​of Soninke society and of African collective memory. When he died in 2009, it was the baobab tree that collapsed, the memory of my company that was in danger of being extinguished. I decided to redo Ganda's last trip, from Paris where he died, to Maréna near Kayes in Mali where he is buried. His old friends will tell us his singular story and, by analyzing the meaning of his words, will make us understand the preponderant place that song and music have in the lives of Africans.
