One of the first Puerto Rican entertainers to achieve world-wide fame was Antonio Paoli Marcano, an opera singer known as "The King of Tenors" and as "The Tenor of Kings." He was the first operatic artist to record an entire opera when he participated in a performance of "Pagliacci" by Ruggiero Leoncavallo in Italy in 1907. The Palmieri brothers, Charlie and Eddie Palmieri, were band leaders in the United States. Rock N Roll Hall of Famer Joe Negroni was a member of the rock and roll group "The Teenagers." Both Américo Boschetti and Vicente Carattini were singers and composers. Carattini composed Puerto Rican Christmas-related songs. Carmen Delia Dipiní was also a notable singer of boleros.
