Maurice Bourbon is a choral conductor and teacher known for his interpretations of early polyphonic music. He is the director of the French early music vocal ensemble Métamorphoses. From its inception in 1983, the ensemble has specialized in French and Italian music from the Renaissance and Baroque. Bourbon leads Métamorphoses with or without instrumental accompaniment, depending on the repertoire. In 1989, Bourbon created Métamorphosis, an academy for the study of polyphonic singing at which Métamorphoses is the ensemble-in-residence. Four years later, Bourbon founded the International Workshop for Vocal Polyphony at Cévennes and the chamber choir Coeli et Terra, and in 2005 the young adult, vocal ensemble Biscantor! He credits his knowledge and thoroughness of analysis to his days as a student and researcher in sedimentology.
