Missa Sancta is the first album in a new CD series. The programme consists of works by Italian masters working at the court of the Polish Vasa kings, Sigismund III and Ladislaus IV. The achievements of Polish composers from the time of the Vasa dynasty, who included artists of such calibre as Adam Jarzębski, Marcin Mielczewski, and Bartłomiej Pękiel, have already been recognised and presented. It is therefore high time to restore and save from oblivion the works of Italian masters to whom we owe the development of 17th-century Polish music in the first place. Of the very numerous musicians who performed in the royal ensemble at that time, the figures of Marco Scacchi and Franciszek Lilius (Gigli) seem to have been most thoroughly studied and discussed by eminent Polish musicologists.
