Eloïsa Matheu and Francesc Llimona left for East Africa at the end of the dry season, when the Blue Wildbeest begin their migration south. They recorded in the big National Parks : Maasai Mara, Amboseli and Kakuru Lake in Kenya, then Serengeti, Ngorongoro and Manyara in Tanzania. The concerts which are successively recorded, aim at recreating the general atmosphere of these landscapes. Different biotopes fuse into one another. Birds are everywhere and sounds interweave.
