'Free improvisation is almost by definition outsider music, opposed to capitalist business-as-usual. Improvisers want to explore the possibilities of the instant - in this space, using these instruments, with this audience (or lack of it)'.

Plenty of music exists simply for itself, without regard to entertaining anyone.
And plenty of art exists for commercial purposes.
