This book could have been less than half the length if the various writers had written what they meant in actual words that mean what they actually mean. There are a few gems among the unintelligible gobbledegook, however. Theodore Adorno's 1941 'On Popular Music,' and Tristan Tzara's 1920 'Memoirs of Dadaism,' are a refreshing dessert after the depressingly overcooked meat of the collection.
