I do not accept as axiomatic that all musical performances and recordings that are for sale are part of the music industry, or what my friend J. calls the Competitive Music Industry. I do not believe that all performances and recordings are in competition with each other, nor that any performances and recordings are in competition with each other unless they opt into the Industry.
In contrast, opting out of the industry provides musicians and their music the opportunity to be heard by a community who shares aesthetic, social, cultural, and political ideals. The fact of the performers and the fact of the audience are literally in concert, qualitatively equal.
