Gary Stewart's book is so very well researched. If you are not familiar with the Congolese Rumba, the material will not really interest you and be difficult if not impossible to read. If you are familiar with this remarkable music in any way, you will end up seeking out and acquiring as much of this music and record titles as you can afford. I must have bought about 150 CD titles of the artists mentioned in the book.Stewart's book puts these artists and their music in the context of a history previously unwritten about in the English language. The only other book that comes to mind is Graeme Ewens' "Congo Colossus", but that title is more confined to the history of Franco (Francois Luambo Makiadi) and Le T.P. OK Jazz.If there is a criticism, it is a small one. He leaves out Orchestra Super Mazemba and Samba Mapangala. Although those artists made their mark in Kenya, they were in fact major Rumba artists from the Congo. However, Mr. Stewart performed remarkable research not to mention a history book that moves like an impossible to put down novel.
