A lot of blues music seems like it's moving away from God, or the center, and Gospel music is moving towards it. It's embracing a higher reality. When you look a little closer, the way that I define it or explain it, is that the blues is the naked cry of the human heart, apart from God. People are searching for union with God. They're searching to be home. There's something in people that seeks this union with their creator. Why am I here? Where am I going? What's it all about? Who am I? All this kind of stuff.
