To my surprise, Hermin Esser not only holds his own in the title role, but delivers some very impressive singing—both in the bombastic forging scene and the more introspective moments of the forest murmurs. Although the Siegfried Brünnhilde is the shortest of the three, it is arguably the most demanding, culminating in an exposed high C. Helga Dernesch just misses that final note, but otherwise gives a compelling performance, particularly notable for the richness of her tone. Zoltan Kélémen dominates his scenes as Alberich., though there are some brief drop-outs—likely from reel changes—that occur during orchestral interludes, preserving the dramatic continuity of the scenes.
