Bari made his debut in 1905 at the San Carlo in Napoli in Rigoletto. In 1906, he returned again to the San Carlo to sing in Rigoletto, Lucia di Lammermoor and Ballo in maschera. During the same year, he sang at the Municipal in Santiago in Chile. Such important beginnings lead us to imagine that he would have a very important career. Surprisingly, Bari developed the rest of his career mostly in minor theaters. He was active into the 1930s.
Most of his recordings were made in 1923 and 1925 for Phonotype. In 1912, he recorded some tests for Edison, some copies of which were discovered, decades later, in an Edison warehouse.
After his career, he taught singing at the San Pietro di Majella conservatory in Naples. Fun fact: In 1947, he gave lessons to a US baritone called John Taber Fitzgerald, who made his debut the next year at New York Town Hall in a long solo concert – at the age of 84!
