Odd that piece didn't actually mention more of the scholarship around this, especially since they reference the "wurlizter" line. The book by Hugh Wilford on exactly that topic was excellent and the bibliography in the back was a gold mine on art, intellectuals, labor fronts, etc. www.amazon.com/The-Mighty-Wurlitzer-Played-America/dp/067403256X/

The Cultural Cold War by Saunders is, as far as I know, the best main stream scholarship on specifically the art scene.

EDIT: ....and I'm an idiot. Saunders is the author of that article. Jesus. Nice find OP.
