References to the Gesamtkunstwerk, a "total work of art," abound in discussions of modern art and culture, often describing a seamless melding of a variety of art forms that overwhelm the emotions, impede critical thought, and mold a group of individuals into a powerless mass. Famously set forth by the composer Richard Wagner in 1849, the term has been applied to such disparate settings as the cinema palaces of Berlin in the 1920s and Andy Warhol's Factory scene in New York in the 1960s. In Modernism after Wagner, Juliet Koss explores the history and legacy of Wagner's concept, laying out its genealogy and the political, aesthetic, and cultural context from which it emerged, and tracing its development and reception through the 1930s. Beginning with Wagner's initial articulation of the Gesamtkunstwerk in the wake of the 1848-49 revolution, Koss addresses a series of linked episodes in German aesthetic theory and artistic practice that include the composer's efforts to build a theater to house his music dramas, culminating in the construction of the festival theater at Bayreuth in 1876; German aesthetic theory and criticism in the visual arts, theater, film, and radio from the 1870s to the 1920s; the founding of the Darmstadt Artists' Colony in 1901 and that of the Munich Artists' Theater in 1908; performances and parties at the Bauhaus in the 1920s and 1930s; and the legacy of the Gesamtkunstwerk under National Socialism. Attending to Wagner's absorption into Fascist aesthetics, Koss foregrounds the revolutionary origins of the Gesamtkunstwerk and its emancipatory potential. Rigorously researched and highly accessible, Modernism after Wagner places the Gesamtkunstwerk at the heart of modern art and culture.
