Wilhelm Richard Wagner: Tristan und Isolde

Wilhelm Richard Wagner was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas. Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionized opera through his concept of the Gesamtkunstwerk, by which he sought to synthesize the poetic, visual, musical and dramatic arts, with music subsidiary to drama. - Wikipedia
