or the Culture Industry. The latter has become a particularly productive, yet highly contested term in cultural studies. Many of Adorno's reflections on aesthetics and music have only just begun to be debated, as a collection of essays on the subject, many of which had not previously been translated into English, has only recently been collected and published as Essays on Music. Adorno's work in the years before his death was shaped by the idea of "negative dialectics", set out especially in his book of that title. A key notion in the work of the Frankfurt School since Dialectic of Enlightenment had been the idea of thought becoming an instrument of domination that subsumes all objects under the control of the (dominant) subject, especially through the notion of identity, i.e. of identifying as real in nature and society only that which harmonized or fit with dominant concepts, and regarding as unreal or non-existent everything that did not. Adorno's "negative dialectics" was an attempt to articulate a non-dominating thought that would recognize its limitations and accept the non-identity and reality of that which could not be subsumed under the subject's concepts. Indeed, Adorno sought to ground the critical bite of his sociological work in his critique of identity, which he took to be a reification in thought of the commodity form or exchange relation which always presumes a false identity between different things. The potential to criticise arises from the gap between the concept and the object, which can never go into the former without remainder. This gap, this non-identity in identity, was the secret to a critique of both material life and conceptual reflection. Adorno's reputation as a musicologist remains controversial. His sweeping criticisms of jazz and championing of the Second Viennese School in opposition to Stravinsky have caused him to fall out of favour. The distinguished American scholar Richard Taruskin declared Adorno to be "preposterously over-rated." The eminent pianist and critic Charles Rosen saw Adorno's book The Philosophy of New Music as "largely a fraudulent presentation, a work of polemic that pretends to be an objective study." Even a fellow Marxist such as the historian and jazz critic Eric Hobsbawm saw Adorno's writings as containing "some of the stupidest pages ever written about jazz". The British philosopher Roger Scruton saw Adorno as producing "reams of turgid nonsense devoted to showing that the American people are just as alienated as
