Disruptive Formalism: The introduction of such dramatically different and effective formal techniques in artwork that they displace or marginalize current formal trends.
Think movements like impressionism or artists like Picasso and Jackson Pollock.
This term is a combination of the art world word "Formalism" and the tech world word "Disruptive" (click through the word to view the Wikipedia article for each).
I feel like Disruptive Formalism is happening constantly in art, though maybe not in such obvious ways recently has it has happened in the past... especially within the disciplines of painting and drawing. I like how in the tech world basically every new idea is evaluated based on whether it will be "disruptive." I don't think that art needs to be disruptive to have merit, but I tend to appreciate artwork that is on the more side (rather than the less side) of innovation. This is why I feel like the idea of Disruptive Formalism should be tossed around more in contemporary art conversations.
