on stage. The same is true for Plácido Domingo, who sang the role of Tristan to critical acclaim in the 2005 EMI release under the baton of Antonio Pappano despite never having sung the role on stage. In the last ten years acclaimed sets include a studio recording with the Berlin Philharmonic by Daniel Barenboim and a live set from the Vienna Staatsoper led by Christian Thielemann. There are several DVD productions of the opera including Götz Friedrich's production at the Deutsche Oper in Berlin featuring the seasoned Wagnerians René Kollo and Dame Gwyneth Jones in the title roles. Deutsche Grammophon released a DVD of a Metropolitan Opera performance featuring Jane Eaglen and Ben Heppner, conducted by James Levine, in a production staged by Dieter Dorn and a DVD of the 1993 Bayreuth Festival production with conductor Daniel Barenboim and featuring Waltraud Meier as Isolde and Siegfried Jerusalem as Tristan, staged by Heiner Müller. More recently Barenboim's production at La Scala, Milan, in the production by Patrice Chéreau has also been issued on DVD. There is also a technically flawed, but historically important video recording with Birgit Nilsson and Jon Vickers from a 1973 live performance at the Théâtre antique d'Orange, conducted by Karl Böhm. In a world first, the British opera house Glyndebourne made a full digital video download of the opera available for purchase online in 2009. The performance stars Robert Gambill as Tristan, Nina Stemme as Isolde, Katarina Karnéus as Brangäne, Bo Skovhus as Kurwenal, René Pape as King Marke, and Stephen Gadd as Melot, with Jiří Bělohlávek as the conductor, and was recorded on 1 and 6 August 2007. A performance typically lasts approximately 3 hours and 50 minutes. Concert extracts and arrangements The Prelude and Liebestod is a concert version of the overture and Isolde's Act III aria, "Mild und leise". The arrangement was by Wagner himself, and it was first performed in 1862, several years before the premiere of the complete opera in 1865. The Liebestod can be performed either in a purely orchestral version, or with a soprano singing Isolde's vision of Tristan resurrected. However, the very first time the prelude and its opening "Tristan chord" was heard publicly was on 12 March 1859, when it was performed at the Sophieninselsaal in Prague, in a charity concert in aid of poor medical students, conducted by Hans von Bülow, who provided his own concert
