Take a perfect cast, a great conductor and a groundbreaking staging in-out makes a 'Tristan' for eternity. The 1983 performance in Bayreuth was a great moment for the world of opera. The ensemble performance of René Kollo, Johanna Meier and Matti Salminen with, then as now the Wagner admirer, Daniel Barenboim conducting the Bayreuth orchestra inspired singers and instrumentalists to peak performance. Jean-Pierre Ponnelle created a dream-beautiful stage.
