One conclusion I took from reading Robert Hughes's The Shock of the New is that avant-garde envelope pushing is not a sustainable phenomenon. The period from the late nineteenth century to the middle twentieth saw a lot of bold art movements, starting with Impressionism and winding up with Abstract Expressionism, with Pop Art being a kind of denouement. This was something of a result of historical circumstances. You had a conservative art establishment at the beginning, sure to take scandalous notice of Impressionist and Post-Impressionist innovations. At the same time it was an artistically literate crowd. The fact that the Bourbons' collections had been made public after the French Revolution helped a lot here.
The art world wasn't as innocent as all that for long, but there was still enough pent-up energy to sustain itself for 80-100 years. But that couldn't go on forever. Successive generations couldn't have the same impact, even if they had brilliant artists among them, because it was already understood that they were free to do anything.
The above picture is by a young painter (born 1993) named Louis Fratino. It made enough of an impression on me that I looked him up. His Wiki page says that he's part of something called "New Queer Intimism" which is "a contemporary art movement inspired by the immediacy and colorwork of Impressionism paired with the intimacy of everyday queer life." And I like some of what I've seen of his painting, but...Fernand Leger and Henri Matisse would have been about as shocked by his style as by his being gay, which is to say not at all.
Which is to say that this "New Queer Intimism" has some talented people associated with it, but the term is by definition tied to aspects of identity more than the process or intent of the work itself. With or without labels, the most rewarded artists of our time have gone all the way back to being Neoclassical. Not, as Jerry and George would say, that there's anything wrong with that.
