In going back to the original high definition video master tapes and using cutting-edge HD encoding technology, Kultur was able to maximize the video quality of this new presentation of this historic Ring for Blu-ray.
This allowed Kultur to exploit the Blu-ray standard to its fullest and to also include three audio streams, LPCM, Dolby 5.1 and DTS 5.1.
The production of Wagner's Ring at the Bayreuth Festival is an event that takes place only once every six years. Bayreuth recordings of the complete cycle are very rare; this being only 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).
