Years ago (1970) in the UK, Columbia records issued an LP called "Savannah Syncopators-African Retentions In The Blues" (CBS 57299) as a companion piece to Paul Oliver's book by the same name (which I haven't read), published in the Blues Paperback Series, by November Books Ltd., published by Studio Vista Ltd. I found a used copy of the recording here in the USA, (where it was never issued). It contains side by side illustrations of American blues and types of African music each selection grew out of, 16 cuts in all, as compiled and produced by Oliver.

Find, read, listen and share his draw your own conclusions. Don't know whether the album or book are still in print, but I gave you what was on the LP jacket. Happy hunting!
