Reading in the NYRB a review by Charles Rosen of Adorno's books on music, recently published in English, I am struck by how dated Adorno's Freudian jargon seems: "infantile," "regressive," "fetish." A Germanic, Hegelian scheme underlies the typical mid-century Marx/Freud mixture. Rosen sees Adorno's dismissal of jazz as sheer ignorance, a position I have long argued myself.
