The German conductor Hans Knappertsbusch and the Bayreuth Wagner Festival were nearly synonymous propositions in their respective performative and historical grandeur by the 1950s, an era also looked back on from the present as a golden age of Wagnerian singing. Furthering these propositions is the splendid Ring cycle of 1957, which hosted Knappertsbusch and a cast of incredible singers including Hans Hotter, Birgit Nilsson, Astrid Varnay, Ramon Vinay and Wolfgang Windgassen, amongst others, spread across these four 24Bit/96kHz re-mastered volumes from Walhall Eternity.
