Richard Wagner Ring des Nibelungen opera cycle performed 2008 at the Deutsches Nationaltheater Weimar and published by Arthaus Musik. Save money by buying all the Weimar Ring operas in a boxed set. The box includes the four titles described in more detail on this site at Das Rheingold, Die Walküre, Siegfried, and Götterdämmerung. See individual titles for individual grades. This set has the Arthaus Cat. No. 101374. My blended grade for the box set is "D+."
The first set of buttons below is for Arthaus Cat. No. 101374, the "old" box. See further below for a newly published box with different artwork. The old box may not be available in the future.
In 2017, Arthaus reissued this item, with new artwork as seen above, as Arthaus Cat. No. 109320. My blended grade remains the same at D+. Shop around. It seems now (June 2017) that the old box will be phased out and replaced by the new box.
