Blue Heron Renaissance Choir (Blue Heron) is a vocal ensemble that presents live performances based on the study of original source materials and historical performance practice. Blue Heron’s principal repertoire interests are fifteenth-century English and Franco-Flemish polyphony, ranging from Dunstable and Du Fay through Ockeghem to Josquin; Spanish music between about 1500 and 1575; and neglected early sixteenth-century English music, especially the rich and unexplored repertory of the Peterhouse partbooks (c. 1540). Since 2010, Blue Heron has been artist-in-residence at Boston College.
