I chose the following from one of his earlier (6th studio release) albums, "Tap Root Manuscript." Diamond's expression of an African sound. It's called, "The African Trilogy." Released in 1970. This is the whole "B" side of that album. The "A" side had his hits like "Free Life" and "Cold Water Morning", and "Cracklin' Rosie."
This would be considered outside of the popular songs Diamond was famous for, but I think it's an example of his musical genius. This man has been a big hit for over 50 years. Check out his music!
