Naples was in the mid-18th century the third largest European city and one of the greatest centers of political, commercial and cultural influence. The conservatoires there were founded by religious orders and were originally intended as charitable institutions for the accommodation and education of orphans, but soon became real centers of musical education and performance; many leading composers were pupils and teachers there and so contributed to the founding of the Neapolitan School. Porpora and Hasse are the greatest representatives of the Neapolitan style and both settled in Venice before rising to international fame. Their writing was strongly influenced by opera and reflects the Italian taste of the time; it is also present in their religious compositions. Les Muffatti and the South-African countertenor Clint van der Linde present works of exceptional expressive power, with Hasse's Hostes Averni and Porpora's Nisi Dominus being recorded here for the first time.
