The most sincere vocalists or musicians I have ever known were always those who do not need to be paid to sing or play. We do it for the passion and the love and the feeling of being content from our heavens to toe!
Of course, if you want one to take time and construct a show that will entertain not only themselves but also fans, there must be some for of compensation and that is not always monetary.
One thing is certain, you never have to pay me to hear me sing. You only need to be in close proximity.
Do what you love and your reward will come from within and your soul will be fed!
