This title is about a single, serpentine fact: late in 1976 a record called Anarchy in the UK was issued in London, an event which launched a transformation of pop music all over the world. The song distilled, in crudely poetic form, a critique of modern society once set out by a small group of Paris intellectuals. In Greil Marcus's classic book on punk, Dadaism, the situationists, medieval heretics and the Knights of the Round Table (amongst others), the greatest cultural critic of our times unravels the secret history of the 20th century.
