After the rousing success of our concert of 18th-century opera arias rescued from obscurity, Clavecin en concert and Julie Boulianne are back with a second series of 10 magnificent arias by an equal number of Mozart contemporaries. Surviving only in manuscript form, they have been revived after several centuries of silence by the joint efforts of Pierre Gouin, typesetting, and Luc Beauséjour, editing[PC1] . Some 20 musicians, conducted by Beauséjour, accompany the glowing voice of acclaimed mezzo-soprano Julie Boulianne.
