Angelo Muñoz is originally from Chile and grew up in the Quebec City area. It was during his High School studies that he was introduced to the trombone and that he began to study at the Conservatoire de musique de Québec under the tutelage of Damien Boivin. Then he moved on to McGill University where he earned a Bachelor's Degree with distinction. In 2001, he completed his studies in Alain Trudel's class at the Conservatoire de musique de Montréal, where he obtained a First Prize in Trombone. During his studies, Angelo took part of the National Youth Orchestra Tour of Canada, of the Spoleto Festival in Italy and, in December 1997, he became Second Trombone at the Orchestre symphonique de Trois-Rivières.

Thereafter, Angelo occupied the position of Principal Trombone of the Shanghai Symphony Orchestra and took part in the Summer Opera Festival of Martina Franca in Puglia, Italy. Back in the country, he became a freelance musician in the province's music scene, working with the Orchestre symphonique de Montréal, the Orchestre symphonique de Québec, the Orchestre Métropolitain and Les Violons du Roy. Angelo Muñoz is a member of the Orchestre symphonique de Laval and, since 2010, a member of the Nouvel Ensemble Moderne, ensemble in residence at the Université de Montréal, dedicated to the diffusion of today's music and to the classics of the 20th century.
