Helen Vanni was an American mezzo-soprano represented in the Pristine catalogue through Leinsdorf’s 1961 Metropolitan Opera recording of Wagner’s Die Walküre.

The performance places her with Birgit Nilsson, Jon Vickers, Otto Edelmann, Irene Dalis and Met Opera forces.

Because wider public biographical detail is limited, this entry remains tied to the recording evidence and its Met Wagner context.
