[2][3][4] After a successful career in South America, Europe, and the United States, De Antonis was incapacitated for more than two years after being hit by a motorcycle in 2012.

De Antonis sang a capella in school and was part of the Unicén Choir, overseen by Bernardo Moroder, who encouraged him to go to Buenos Aires to study.

[9][10] He also spent time studying abroad in Italy, France, Spain, Germany, and the United States[7] with teachers including Frank Scioli,[1] Andres Risso, Oscar Ruiz, Natalia Biffis, and Sofía Galicia.

He performed in opera houses across 43 cities in Germany and at the closing of the World Class Polo 2000 and the Grand Ball in Berlin's Adlon Hotel.

Over the next few years, he toured across Germany, France, Italy, Spain, Mexico, Argentina, Canada, Denmark, Uruguay, Chile, and the United States.

[16] He debuted at the G. Verdi Conservatory[14][1] in Milan in 2006 and played Count Almaviva in The Barber of Seville, Rinuccio in Gianni Schicchi, and Rodolfo[16] in La bohème.

Werner was interested in moving into the music industry and spent six months convincing De Antonis, who was already enjoying success in Europe, to come to Los Angeles.

[16] De Antonis was one of the performers, along with Michael Bublé, Diana Ross, Reba McEntire, Josh Groban, and Neil Sedaka, at Celebrity Fight Night XIII in Phoenix, Arizona in March 2007.

[6][5][7] Bankrupt by medical bills due to lack of health insurance, he relocated to Miami and started driving for Lyft and Uber.

[4][22] Since appearing on America's Got Talent, De Antonis has visited schools[2][23] and performed at a number of events,[24] including as a guest chef at the Friendship Circle's Culinary Club in 2023.
