Polyphonic ensemble Dionysos Now! is not sitting still. As an extra to the Adriaen Willaert Series, they release a live recording of Maistre Jhan's Missa Inviolata. The mass was live recorded in Mauerbach, Austria.

Maistre Jhan, a French composer, worked from 1512 at the court of Ferrara for the Duke Ercole d'Este (and later for Alfonso d'Este). First as a singer, then as Kapellmeister, and remained there until his death in 1538. The title of the mass 'Inviolata' refers to the model on which the mass is built: the well-known motet by his contemporary Josquin Deprez 'Inviolata, integra et casta es Maria'. Several musical themes from the motet are quoted in the mass, as a tribute to his fellow musician.

Design of the artwork is based on 'zonnebloem' (2004) by Francky Cane.
