in the Raverty sort of direction

Here's a title I enjoyed and that you might find useful:

The New York Schools of Music and Visual Arts (2002).  Edited by Steven Johnson.  Routledge.  ISBN:  0415936942

Doesn't essay directly on Pollock but has 20 references to his name in the index.

I got it for the discussion on John Cage who was part of this scene.   The cover has a vintage picture of the Cedar Street Bar on it.

Another angle:

I have some CD's of Morton Feldman's music.   I wonder if examining Pollock through a musical lens might be sustainable?
