German composer Richard Wagner wrote Parsifal, which is a three-act opera that tells the story of the title character's quest to save the Knights of the Holy Grail by returning the Holy Spear, healing King Amfortas, and carrying out the sacred ceremony of uncovering the Holy Grail.

Frank Castorf revolutionised German-language theatre in the post-Berlin Wall era, bringing to the stage intellectual and political acuteness, brash references and a not infrequent use of crude humour. He brought these qualities to the Bayreuth Festival where his production of the Ring ran from 2013 to 2017. This 2016 recording of Das Rheingold captures Marek Janowski's festival debut as conductor of this unique production, in which Castorf replaces the Rheingold with oil as the central commodity in a pre-capitalist society. The first night of the Ring cycle begins at a gas station off of Route 66, the main road connecting the East and West coasts of the USA, that played an important role in commerce in the 1920s.

Frank Castorf's Ring makes a feature of unexpected settings and striking images, and here in Siegfried he shows the discussions between the young hero and his foster father Mime in Act I against a background featuring giant heads of Marx, Lenin, Stalin and Mao on a replica of Mount Rushmore. The typical mythical nature and forest world of the second act is replaced in this production by Berlin's Alexanderplatz. The Nothung sword is also replaced, in this production becoming a machine gun. While the direction elicited both approval and disapproval, the vocal performances received wide acclaim.
