Really, what is the point of it all? Schlepping equipment all over town; up and down flights of stairs or through tight corridors that are clearly against the Fire Marshall's code; wine stained clothes from patrons/fans who had just a little too much to drink, strange men, strange women, men and women who might be a little too familiar, loud laughter and even babies that are crying so loudly that you can't hear yourself think, children who's parents allow them to run through the venue like they are on a playground, etc. etc. etc. ad nauseum.
Well, I'll tell you what my opinion is. The point of it all is that Music was meant to be shared. Music was meant to be created and given away. Music is a gift. You learn it, you might write it, you perform it, you record it. But if no one ever hears it then the gift will wither and die. That's why we all go through the insane things we go through to perform in front of a live audience. Because for the most part - we're givers. Also receivers. There's nothing like giving a song to an audience and having that circle of energy moving back and forth and back and forth and to and fro during the performance. You give and they receive and by receiving they give and so on and so on and so on.
Music is a gift. Share it. Receive it. Learn from it. Pass it on. Play it forward.
