Astrid Varnay : Astrid Varnay: Wagner - Die Walküre, 'Siegmund! Sieh auf mich!'
Ibolyka Astrid Maria Varnay (25 April 1918 -- 4 September 2006) was an American dramatic soprano of Hungarian heritage and Swedish birth, who did most of her work in the United States and Germany. She was one of the best-known Wagnerian heroic sopranos of her generation. Her voice on record is readily recognisable by its seemingly limitless upper register... http://en.wikipedia.org/wiki/Astrid_Varnay
Ramón Vinay (August 31, 1911 [some sources say 1912] -- January 4, 1996) was a famous Chilean operatic tenor with a powerful, dramatic voice. He is probably best remembered for his appearances in the title role of Giuseppe Verdi's tragic opera Otello... http://en.wikipedia.org/wiki/Ram%C3%B3n_Vinay
