It's amazing how the roots of blues spawned many styles
of music that's still loved even unto this very day.
I know when we(some of us) want to get at someone, if we're angry, we sometimes say the first thing that comes to our minds. In many instances we will go for the "country ass" comment for the lowest shot.
So much of the music that we love to dance to is rooted in southern blues. I was just reading over this article in this link and it was just another reminder, for me, of that fact.
