Roswell Rudd, the greatest free-jazz trombone player, comes to Bamako, Mali, for one month to play Thelonious Monk to griots from Bamako. On the African side, Toumani Diabaté, genius of the Kora (African harp), teaches his African melodies. "Bamako is a miracle" reveals the backdoor of fusion processes through the recording of a CD with producer Verna Gillis - who launched Salif Keita and Youssou N'Dour. The film shows how much the musical creation puts you always on the edge with the obvious conflicts and also the magic of a two cultures merging.
