In the Fifties, there were ten singers of African Jazz in Bulawayo, a beautiful town in then Southern Rhodesia. They had created two groups, The Cool Four and the Golden Delicious Rhythm Crooners, and they sang all night in the taverns. Life, death, and the fight for the independence of their country separated them for many years. Today, in Zimbabwe, only three survive. Now in their sixties, Abel, Ben and Lucky have revived the music of their beginnings. In the manner of Buena Vista Social Club, Blue Sky recalls the history of these singers by means of archival images, interviews and performances.
