Kirsten Flagstad, the voice of the 20th century who managed to defeat the 'fake news' that linked her to the Nazis. The translation into Spanish of the biography of the legendary Wagnerian soprano written by Ingeborg Solbrekken offers an admirable testimony of overcoming the official lies about an enormous singer.

Flagstad became her biggest star and even her economic lifeline. She sang in almost 250 performances of Wagner's major operas (from The Flying Dutchman to Parsifal ) alongside Beethoven's Fidelio.
