Rok, Ali's music was traditional African music, it was unrelated to our blues in lineage, and the similarities in sound was a coincident. Music is the universal language when it comes to expressing emotions; while our words are different, when it comes to basic emotions, they have similarities in music from around the world, consequently we have "blue" sad music, that could be the same in Africa.
Every since someone's trolley jumped the tracks in regard to all those far fetched relationships, you guys have been hearing things; next, someone will illustrate how chitlins are related to truffles.
Enjoy the music.
