Wagner's intense music drama, a genre he described as "deeds of music made visible".
Centred around the Cornish legend of Tristan and Isolde, whose love is only consummated in death, the prelude to the opera includes the famous chord which has intrigued musicologists and audiences alike. Recorded earlier this year at the Bayreuth Festival.
