How to refer to something that is beyond postmodern?

Here are a few common amalgamations that use 'post' to mark a new reference point:

modern art -> postmodern art

modern portfolio theory -> postmodern portfolio theory

This is all very intuitive. But suppose that we have a need to add another reference point to show that something is more recent than "post." I initially considered "post postmodern art," but the repetition of words comes off as slightly brute force. I'm hoping there is a more elegant solution for this.

Solution 1:

Perhaps, you could use cutting-edge to describe such things:

The latest or most advanced stage in the development of something.

researchers at the cutting edge of molecular biology

Stem cell experimentation, for example, is a complex, multifaceted enterprise that advances at the cutting edge of scientific understanding.
