That's one strength that Stevie has. She's really not a strong instrumentalist in any way. Her instrument is her voice and her words. And it keeps her focused on the very center of that.
I did an album a long time ago called 'Replicas ' which was entirely science-fiction driven or science-fantasy. Since then it's been a song here a song there. It's not really a constant theme. I've written far more about my problems with religion with God and all that.
