Various Artists - The Colón Ring - Wagner in Buenos Aires (Blu-ray disc)

Hans Christophe von Bock's documentary follows the attempts to stage an edited, one day version of Wagner's epic opera cycle at the Teatro Colón in Buenos Aires. Arriving in Buenos Aires to prepare the groundwork for the production, Wagner's great-granddaughter, Katharina Wagner, who now runs the Bayreuth Festival, discovers that the rehearsal conditions are not what she expected. At short notice, she decides to entrust the staging of the production to Valentina Carrasco, who has previously worked with the Catalan theatrical group 'La Fura dels Baus'.
