Wagner's stage directions are notorious: giant dragons; underwater singing; horses on stage; storms; destruction by raging fires. Designer Peter Mumford and Dr John Snelson of the ROH discuss the solutions available to 21st century artists and some famous 19th and 20th century stagings. Presented by Anne McElvoy and including readings by David Rintoul. Recorded in front of an audience at the Royal College of Music as part of this year's Proms Plus events.
