That is the true joy of being a solo artist. I can do whatever I want. I can go wherever I want. I can show up with my guitar and my song, and it can sound a hundred different ways. That's the freedom of being on your own. The flipside is: That's you on the cover. If it sucks, it's your fault.
My mother had a great vinyl collection, and she was constantly playing female singer-songwriters. I first learned about classic song structures by listening to them, and Laura Nyro particularly stood out. Her voice was outside what you'd usually hear on the radio; that really appealed to me.
