Three of the lead singers here (Windgassen, Stolze, and Hotter) were in Solti's classic studio performance of this opera. They are just as good on this occasion, better in fact because they are in a live performance and can be more spontaneous. Stolze's cackling Mime will not please some, but I think he brings the lovably evil dwarf to life. Both Windgassen and Hotter are in good voice and pace themselves admirably.Shuard sings a beautiful Brunnhilde, the voice steady and sure. On this occasion she may have been slightly indisposed as her top notes aren't as confident as they normally were. She gets the C in "Ewig war ich" by the skin of her teeth, nails the three high Bs securely, but ducks the final (admittedly optional) C. Langdon continues his role of Fafner from Das Rheingold and his firm, deep bass suits the role well. He doesn't bother with the scripted yawn or roars though, a little disappointing. Joan Carlyle not only sings beautifully as the Woodbird, but one can actually understand her words - no mean achievement as the text is difficult to articulate. With her rich contralto, Guy is terrific as Erda as is Kraus as Alberich. Solti is less fussy than he is in the studio recording.The sound may not be sumptuous, but is very listenable. I look forward to the Gotterdammerung from this cycle!
