Music is a very potent voice for your ideas, make a movement, best of luck to you. What would "(over)correction" be? I don't think you should fear a change of guard, Post-Modernism will have its place in the history of art like any other, replaced by something more vital and relevant for its time. There's probably still some ghostly geezer out there trolling the Musee D'Orsay hoping to get a whack at Manet's Olympia. Hope we're not derailing.
