The premise of the series of paintings sampled in this video, collectively titled 'Body of Work', is that the production of art is part of a continuum that involves every sector of society. This chain stretches from the manufacture of raw materials, to the maintenance of cultural venues, to the discourse that shapes a work's valuation in history.
The artist is one participant in the midst, not sealed off from other social activities.
This is a healthy state of affairs, an ecosystem. It's also an appropriate subject for painting.
