There have been rumors for years that the First Act of this Siegfried is actually from Krauss' cycle broadcast a few weeks later. Since the singers are the same in both it's difficult to tell whether or not that is true. Hearing again it does seem to me that's it's the same performance (Windgassen makes the same mistakes and the audience noise is the same.) In any case this is a superb Siegfried. Yes, Windgassen makes a few musical errors (this was his first time out in the role), but otherwise he is magnificent, the voice steady, fresh, and beautiful. He also conveys Siegfried's narcissistic personality very convincingly. Kuen is a slimy Mime albeit one who doesn't stick to the notes as much as one might like. He and Neidlinger are a hoot in their scene together. Hotter is in confident, strong voice and Greindl is a frightening Fafner who happily yawns and roars with aplomb. Streich is a heavenly Woodbird, Ilosvay remains an impressive Erda. Modl continues to be in superb voice, nailing all the top notes (including a triumphant final C.) Again, she is in more confident vocal form here than she would be for Furtwangler in the RAI recording. Keilberth's conducting continues to be well-placed. I was never bored as I have been with other conductors in this music.The sound is extremely good broadcast mono. The disc break between 1 and 2 is unfortunate, but otherwise they make musical sense. All Wagner lovers should hear this performance.
