I like listening to old blues like the stuff played by Lead Belly, Robert Johnson, Blind Willie Johnson, John Hurt, Elizabeth Cotton etc.
Just listening to that music can give a person a pretty good appreciation for history. Just listening to the old stuff it is clear that the slaves that came to the USA were basically playing a country version of the blues and they also sang gospel. Well country music, folk music and blue grass seem to be offshoots of those country blues, which was originally played on banjos that the Africans brought to the USA. When the slaves were sold down river from the Upper Southern States in the USA to New Orleans they took the blues with them, which became jazz after the slaves were introduced to French brass horn instruments.
Country Blues then became harder edged which ushered in the electric Blues, which eventually became Rock and Roll and Soul music. Soul music split into three different music: Funk, Disco and R&B. The point is that the music just keeps splitting, but it all stems from the Blues. I can tell that you have an appreciation for music.
