I like the post, but back Drew who finds merit in the sense of play, playing with structures, poking the eye of them, yet ultimately relying on them as the thing which is kicked against, and provides the material. I don't think that necessarily has to mean a willingness to dismantle those structures. I can see where there would be correlation between postmodernism and nihilism in the recognition of the lack of value, in your personal response, to these things, but one can still recognise the value others place in the structures, and indeed that's part of the charm of mashing them up and wilfully baffling an audience. I see a closer connection to existentialism than nihilism, in fact, because it's taking in all culture and input within a single moment and trying to respond to it in a single moment. But these are broad generalisations I'm making due to lack of time, sorry.
