I was reading this article about session musicians, and I was wondering what is going to happen to them as a result of file sharing. Some very talented musicians have created some great work in anonymity. If albums are no longer profitable, and become more of an advertisement that induces you to spend money elsewhere, like say going to concerts, it seems like it will be harder for session musicians to make a living. I don't know the answer, I was just thinking about a group of musicians who gets left out of the whole downloading debate.
