Betrayed and alone, Tristan lies wounded in his castle of Kareol. As his strength ebbs, he sees fantastic visions and dreams that the love of his Isolde might still redeem him. And so it will:
but in a way more terrible, and more beautiful, than either of them had imagined. In the final act the music verges on the transcendent - though not before we’ve confronted the darkest implications of Wagner’s world-changing vision, in Richard Strauss’s wordless war-requiem for strings, Metamorphosen.
