Reading

"In fact, a book or a composition is not an end-product, not in itself a useful commodity. The end-product of an artist's work, the 'useful commodity' in the production of which he plays a role, is ideological influence. He is as incapable of producing this on his own as a blacksmith is of producing Concorde. The production of ideological influence is highly socialised, involving (in the case of music) performers, critics, impresarios, agents, managers, etc., and above all (and this is the artist's real 'means of production') an audience."  

-Cornelius Cardew
