“Angel Blue doubted her path to opera”. Now he’s a star.

Moments before taking the stage in “Aida” at the Metropolitan Opera on a recent evening, soprano Angel Blue was in her dressing room, smiling and blowing kisses during a livestream for fans.

Blue, who sings the title role in “Aida,” was emotional, telling her followers that she was thinking that evening of her father, Sylvester, who died in 2006 and who, as a musician, helped her to be interested in opera. She said she sang for him, for his fans and for herself.

“I pray and hope that your dreams come true,” she said. “The things you want are at your fingertips, if you will believe it. I know I believe it, and I continued to believe it. And I’m fulfilling all my dreams right now being here at the Met, singing this great opera.

Blue, 40, a former model and beauty queen from Apple Valley, Calif., once doubted her path into opera, discouraged by a wave of rejections early in her career.

But she is now a regular on the world’s biggest stages, including at the Met, whose new production of “Aida” will be simulcast in theaters around the world on Saturday. In this opera, she found a decisive role. Blue received critical acclaim for her shimmering voice and the intensity of her portrayal, and she received acclaim from her colleagues in the operatic field.
