Bruson's passion for music matured in the parish choir when he was a child. He began his music studies at the conservatory of Padua where he was awarded a scholarship that allowed him to attend the courses in the face of economic problems. He did not receive much support from his family, who considered him a good-for-nothing. In his own words: "They thought that I only wanted to study music because I had no desire to work. At that time, the general feeling where I lived was that if someone worked, they had a future, whereas those who studied, especially if they studied music, were considered failures who would never find their path in life." However, he could continue his studies with the help of the administration of the conservatory and the support of friends. Bruson made his operatic debut as the Conte di Luna in Il trovatore at the Teatro Lirico Sperimentale in Spoleto in 1960. The following year he was Riccardo in I puritani at the Teatro dell'Opera di Roma in Rome. His first Metropolitan Opera appearance was as Enrico in Lucia di Lammermoor in 1969. In 1970 he started his collaboration with conductor Riccardo Muti in Un ballo in maschera in Florence. He made his debut at La Scala in 1972 as Antonio in Donizetti's Linda di Chamonix, at the Edinburgh International Festival in 1972 as Ezio in Attila, at Covent Garden in 1975 in the role of Renato in Un ballo in maschera, substituting with great success for Piero Cappuccilli. He debuted at the Vienna State Opera in 1978 with Macbeth, with such a success that the prestigious Austrian theatre awarded him with the important title of Kammersänger. In the 1980s he turned to the 18th century with Mozart's Don Giovanni and to Italian verismo with Umberto Giordano's Andrea Chénier. He is considered by some critics the finest Rigoletto since Tito Gobbi. They appreciate his elegant and expressive phrasing, velvety tone, musical intelligence and acting qualities. He excels in long, lyrical lines. He is also appreciated for not disdaining smaller roles and for not assuming a diva attitude. Bruson once described himself in the following terms: "I am self critic enough to understand what I can get at. Since I knew I did not have a thundering voice to make coarse effects, I sought the interpretation since I think it is more important that the publicgo home with something in their hearts than some sounds in their ears". He can be seen on commercial DVD in the role of Macbeth in a performance from the Deutsche Oper with Mara Zampieri and James Morris.
Music critic [Christian Springer wrote of Bruson: "Bruson was the quintessential Verdi baritone in the second half of the last century. A Verdi baritone not as it was understood in the 1950s and 1960s, but a Verdi baritone as understood and desired by the composer himself."
