From the very heart of Africa - Nairobi - comes a ‘call’, that will turn into a great and unforgettable celebration of music and friendship. The concert is dedicated to the people living in the slums grown on Nairobi’s outskirts and meant to raise awareness as well as concrete support for some projects for the economical and social development of Kibera, the biggest slum in the sub-saharan Africa. Riccardo Muti conduces the Youth Orchestra “Luigi Cherubini”, the Italian Youth Orchestra, young musicians of the Nairobi Youth Orchestra, including the joyous contribution of the young artists (ex street children from Kibera and other slums who have been welcomed and helped by the numerous Italian missionaries working in Kenya) who perform acrobatics, songs, and music with their traditional percussion instruments.
