When Daniella Mass stepped onto the America’s Got Talent stage, she was introduced as a talented singer from Barranquilla, Colombia. To the judges, she was a complete unknown. They had no idea they were about to witness one of the most unforgettable vocal performances of the season.

Behind the scenes, Daniella already had an impressive musical background. She could sing in six languages—Italian, French, Portuguese, Spanish, English, and Japanese—and possessed an extraordinary four-octave vocal range. She had also earned recognition by winning the George Gershwin International Music Competition.
