This production of Wagner's The Ring at the Bayreuth Festival is an event that takes place every six years. Bayreuth recordings of the complete cycle are rare; this is the second filmed version. The Kupfer/Barenboim Ring was performed over a five-year period and recorded at the conclusion when the "Bayreuth Workshop" had raised "the quality of the performance to an almost unsurpassable level" (Der Tagesspiegel). John Tomlinson stars. Daniel Barenboim conducts.
