The splendour of Mozart’s motet Exsultate, jubilate stands out in a repertoire that has for too long remained in the shadows: the magnificent output of church music composed in 18th-century Milan, the city in which Mozart, then not even 17 years old, wrote his first masterpiece of sacred music precisely 250 years ago. The virtuosity and melodic beauty of that score, conceived for the celebrated castrato Venanzio Rauzzini, can finally be heard alongside the brilliant works – for soloists and choir, in both the stile antico and the new modern manner – composed for the exacting noble patrons of the capital of Austrian Lombardy by musicians of great refinement and talent: names that include the universally renowned Johann Christian Bach, Giovanni Andrea Fioroni, the then maestro di cappella of the cathedral, and the hitherto obscure Melchiorre Chiesa.
