I'm presenting this because I read a book that never existed. I read a book in the 80's that was hundreds of years old; the title was "Diary of a Slave Trader". It was the kind of book that once you began reading it, you had to keep on reading until the end. The book was very detailed and explicit; it gave graphic accounts of the ugly events involving capturing and transporting slaves across the jungle and across the ocean.
Recently I looked for that book, and there is no record that said book ever existed. It had the names of the African Kings who ordered the slaves. They were the people the slave trader worked for. The Africans who are descendants of those kings are very wealthy and had enough money to erase that book out of existence.

The rhythms we are discussing came from those slaves.
