Marcuse and Art

I have just been reflecting a little on Marcuse's aesthetics in his book The Aesthetic Dimension . According to Marcuse, in modernity art has been institutionalised in a way that legitimates a particular kind of 'disinterested' comtemplative attitude towards the world. As such, art possesses a certain kind of autonomy from society and politics athat allows it to stand as their critic. More specifically, art, in Marcuse's view, has the power to negate society as it currently exists by offering a kind of escape from an oppressive society into oneself and one's own experience. I was wondering whether anyone might provide specific examples of art works that have provided just this function for them, a kind of interior escape into another world, a world that this one might in fact one day become?
