Nadine Sierra first came to my attention some years ago while researching an article about singer education for Opera News. At the time, she was an apprentice in the Adler Fellowship Program at San Francisco Opera. In conversations with various educators and administrators, Sierra’s name kept popping up as an example of an aspiring singer with the rare combination of qualities to succeed in classical music. Those were prescient impressions. In the few years since, the delectable Sierra’s luminescent soprano voice has conquered the Metropolitan Opera, Paris Opera, Berlin State Opera, and that pinnacle of vocal accomplishment, Milan’s La Scala, among many others.
