Nadine Sierra Soprano When American soprano Nadine Sierra was a small child, she saw a video of La bohème and promptly fell in love with opera. She took her first singing lessons at the age of six. She made her debut at the Palm Beach Opera before continuing her studies in New York. In 2017 she won the Richard Tucker Award and in 2018 the Beverly Sills Award in New York. This opened opera house doors throughout the world to her and she has sung in cities including New York, Milan, Paris and Berlin. Falstaff, Rigoletto and West Side Story have been some of her latest engagements. This will be her Liceu debut.
