Just looking at the tracks, this is a documentary of Der Ring des Niebelungen. The other Ring on sale for $550 is the full performance. Das Rheingold by itself is over 2 hours long, not 62" as per this set. Nevertheless, it is uncommon to find this particular documentary by Peter Bassett, and to my knowledge it is not available on any streaming service. It is more common to find the well known documentary by Deryck Cooke. It is well worth adding to the collection of any fan of Der Ring, or anybody who wants to get to know it. GLWTS.
