before and after its relocation to the United States. Though Adorno was not an Institute member, the journal published many of his essays, including "The Social Situation of Music" (1932), "On Jazz" (1936), "On the Fetish-Character in Music and the Regression of Listening" (1938) and "Fragments on Wagner" (1938). In his new role as social theorist, Adorno's philosophical analysis of cultural phenomena heavily relied on the language of historical materialism, as concepts like reification, false consciousness and ideology came to play an ever more prominent role in his work. At the same time, however, and owing to both the presence of another prominent sociologist at the institute, Karl Mannheim, as well as the methodological problem posed by treating objects—like "musical material"—as ciphers of social contradictions, Adorno was compelled to abandon any notion of "value-free" sociology in favour of a form of ideology critique that held on to an idea of truth. Before his emigration in autumn 1934, Adorno began work on a Singspiel based on Mark Twain's The Adventures of Tom Sawyer titled The Treasure of Indian Joe, which he never completed; by the time he fled Hitler's Germany Adorno had already written over 100 opera or concert reviews and 50 critiques of music composition. As the Nazi party became the largest party in the Reichstag, Horkheimer's 1932 observation proved typical for his milieu: "Only one thing is certain", he wrote, "the irrationality of society has reached a point where only the gloomiest predictions have any plausibility." In September Adorno's right to teach was revoked; in March, as the swastika was run up the flagpole of town hall, the Frankfurt criminal police searched the institute's offices. Adorno's house on Seeheimer Strasse was similarly searched in July and his application for membership in the Reich Chamber of Literature denied on the grounds that membership was limited to "persons who belong to the German nation by profound ties of character and blood. As a non-Aryan," he was informed, "you are unable to feel and appreciate such an obligation." Soon afterwards Adorno was forced into 15 years of exile. Exile: Oxford, New York, Los Angeles After the possibility of transferring his habilitation to the University of Vienna came to nothing, Adorno considered relocating to Britain upon his father's suggestion. With the help of the Academic Assistance Council, Adorno registered as an advanced student at Merton College, Oxford, in June 1934. During the next
