a long passage but with specific questions ^^

'It is interesting to note that the Left, which prides itself on its critical approach to late capitalism and is unrelenting and unsparing in its analysis of our other cultural phenomena, has in general given rock music a free ride. Abstracting from the capitalist element in which it flourishes, they regard it as a people's art, coming from beneath the bourgeoisie's layers of cultural repression. Its antinomianism and its longing for a world without constraint might seem to be the clarion of the proletarian revolution, and Marxists certainly do see that rock music dissolves the beliefs and morals necessary for the liberal society and would approve of it for that alone. but the harmony between the young intellectual Left and rock is probably profounder than that. Herbert Marcuse appealed to university students in the sixties with a combination of Marx and Freud. In Eros and Civilization and One-Dimensional Man he promised that the overcoming of capitalism and its false consciousness will result in a society where the greatest satisfactions are sexual, of a sort that the bourgeois moralist Freud called polymorphous and infantile. Rock music touches the same chord in the young. Free sexual expression, anarchism, mining of the irrational unconscious and giving it free rein are what they have in common. The high intellectual life and the low rock world are partners in the same entertainment enterprise. They must both be interpreted as parts of cultural fabric of late capitalism. Their success comes from the bourgeois's need to feel that he is not bourgeois, to have undangerous experiments with the unlimited. He is willing to pay dearly for them. The Left is better interpreted by Nietzsche than by Marx. The critical theory of late capitalism is at once late capitalism's subtlest and crudest expression. Antibourgeois ire is the opiate for the Last Man.'

the highlighted sentences are the hardest to understand.... please tell me what those sentences mean thanx... i posted this question on a few days ago but someone told me i had to be more specific in my inquiring...please explain those three sentences highlighted above for me thanx ^^

Oh and just one more question... why would the bourgeois want to feel that he is not bourgeois?
