She likes to consider herself an Ambassador of Jazz. Miles Davis, though marriage to her cousin, Cicely Tyson, has been a great influence throughout her career. Because of jazz, she has seen countless countries. Like spreading the gospel, she says: "There are people all over the world connected by jazz. In any country and time there is jazz. There is no separation between people. We may not all speak the same language, but we understand the music. It's all intertwined. We all play the tune together". St. Joan expounds soothingly but passionately, "Jazz comes from the spirit not the intellect. That's what is so beautiful about music. Sound is more of a feeling than an idea". Her music is like being baptized by a spiritual sound that makes you a rapt follower. Keisha wants to show you Light in a dark world.
