I like the way this conversation has touched on a controversial subject. Music is life and life is real. Now we can get back to real music, and let the music speak for itself, in regard to "all subjects" without highlighting any other subjects separately.
Nina Simone might be my favorite vocalist. Her musical life began in church, and she also studied and worked hard to become a concert pianist. She was playing piano at a lounge to pay for her schooling as a concert pianist, when the owner asked her to sing. The rest is history.
Since everyone knows all about her vocal talents, I'll focus on another aspect of the talented Ms. Nina Simone. That gal plays a mean jazz piano, and it's so unique, that the only other pianist I can compare it to is "Bud Powell". I've compiled a list of some of her instrumental contributions to jazz. "African Mailman", "Flo Me La", "Nina's Blues", and "Blues On Purpose" are a sampling of her prowess on jazz piano.
Enjoy the music.
