Yes, I'm sure your right zmjezhd, but what's in a date? Things start somewhere at sometime and it to call it all over is never quite true. Currents once started move on upground or underground. You can call Magritte a DADA man if you want. Once Art was declared dead it lived on happily ever after.
Philosophers may claim postmodernism (thePook) as their sublime invention, however choatic it alll may be.
Artist claim it as their invention, it's just nothing new. The
tiranny of 'New!' and the label 'New!'just overrules the fact that hardly anything presented as such is no more than a variation on an old theme. If the variation is interesting and
passionating to see or hear or read ... than what more do you want?
