As a concert master and operetta singer, he toured Europe with a group of musicians. He settled in Albania in 1935, and started to expand on his artistic reputation, being widely esteemed for his accomplished interpretation of classical arias and folk songs. A recording of folk songs done for the Columbia society in 1942 was largely arranged by Pjetër Dungu. Antoniu was the director of the first Albanian opera, Mrika, composed by Prenk Jakova.[1]
