Opera Bobb tells us:
"Ciao, Opera Mavens. At the end of the La Scala Rigoletto second act last night, the standing ovation audience demanded former Adler Nadine Sierra (Adler 2011-2012) and Leo Nucci repeat the final aria (conducted by SF Opera Music Director Nicola Luisotti)."
Nadine is a raging success everywhere these days. For my encounters with her in San Francisco:
Her performance in a Merola final here.
Her Schwabacher debut recital here.
She sings Lucia here.
And now see it for yourself.
