reenactment vs commemoration

Here is another video by PRANGSTGRÜP

This one is called Reenactment Club. "This is not performance art. This is commemoration."

I really like this idea of commemoration (an observance or celebration designed to honor the memory of some person or event) instead of art. Even though in reality, it is a performance about pretending to not be a performance (kind of in a mocking fashion, too). This one gets a very different reaction from the crowd, one almost of pity.

What do you think about reenactment vs commemoration?
