The acclaimed 1995 Bayreuth production of the Wagner opera by Heiner Müller, conducted by Daniel Barenboim with fire and sensitivity. Siegfried Jerusalem and Waltraud Meier were the Tristan and Isolde of choice throughout the decade, and were at the height of their interpretive powers. Müller and stage designer Erich Wonder have compressed the monumental story into a clear and fascinating geometry of love, creating highly evocative spaces through projections of colors and forms.
