I'm going to be making a demo soon of Traditional Folk songs (accompanying myself on guitar.) After the demo is completed, should I have it copyrighted before sending a copy to the independent record labels (the label heads have heard me sing live, and want to have a demo to listen to as well.) My voice is my main instrument, but, I'll play the guitar as well. My songs and guitar work is prepared. Any tips for a first timer in the recording studio?
