“When we first sang together five years ago, as the echo of applause was still ringing behind the stage curtains, they asked my opinion of the young soprano with whom I had just performed. In front of the television cameras, I responded: “I really wanted to sing with her, and today it happened.” Since then, Nadine Sierra and I have trodden the boards of many theaters and performed many duets, as her international career continues to flourish and reap success. She is one of the most talented singers working today.” - Andrea Bocelli
