Slavoj Žižek recently gave five talks under the title Masterclass - Notes Towards a Definition of Communist Culture. It sez 'ere, "The master class analyses phenomena of modern thought and culture with the intention to discern elements of possible Communist culture. It moves at two levels: first, it interprets some cultural phenomena (from today’s architecture to classic literary works like Rousseau’s La Nouvelle Heloise) as failures to imagine or enact a Communist culture; second, it explores attempts at imagining how a Communist culture could look, from Wagner’s Ring to Kafka’s and Beckett’s short stories and contemporary science fiction novels." Audio of Zizek's talks and subsequent discussion is now online: Part I Utopias; Part II Architecture as Ideology; Part III Wagner’s Ring as a Communist narrative; Part IV Populism and Democracy; Part V Environment, Identity and Multiculturalism. Those who like to watch the beard in motion will find links to video of some of the talks posted here.
If you're in a hurry or just don't care much for opera, here's Richard Wagner's "Ring der Nibelungen" in 45 seconds (SYTL). Also a good chance to brush up on your German.
