Tom Service explores classical music’s ultimate binge-listening box set - Richard Wagner’s apocalyptic four-part 16-hour marathon music drama, The Ring.

Selfishness, deception, hypocrisy, greed, destruction; like all good box sets they’re all in there, but what’s The Ring really about? And what can we, and perhaps today’s world leaders, learn from it?

Tom has half an hour to find out.
