Working inside the music industry
As a professional musician I know the music industry very well. The degree of positivity and progress making your music freely available has done which always completely negates any amount of “harm” that may come your way. Getting exposure is king. In short; if they know your music you have an audience. They will come and watch you, they will support you. Building a fan base is more important than sales on each CD or download. When you have a following they buy your music and merchandise because they want to feel a part of the music, it's about treating them as not as customers but instead, people with the same interests.
