Art Contrarian's "Art Adrift"

Donald B. Pittenger, who writes Art Contrarian, has released his book on Kindle. A description:

Art Adrift deals with a crisis of modern painting largely ignored in art history books. What happened was that modernist painters essentially stopped making major innovations by 1920 because nearly every alternative to the rejected traditional styles of painting had been tried. Yet it was believed by modernists that to become famous, an artist had to be creative in the manner of Picasso and other painters behind the art movements that bubbled up in the early 1900s. The problem of having to innovate when innovation was barely possible led to a period of comparative creative stagnation of the avant-garde between the world wars.
