The production of the award-winning composer Carlo Alessandro Landini is enriched with this publication of a sacred page – not common for the maestro – of rare difficulty. Difficulty due not only to the essence of a text like that of a mass, so full of substance and meaning that it makes your wrists tremble at the idea of translating them into music, but also to the inevitable confrontation with the greatest geniuses in history who, from the Middle Ages to the present days, have tried their hand at this genre. Landini uses for his work an a cappella vocal group (the Ensemble Fleur-de-Lys, directed by maestro Giorgio Ubaldi), in a sort of return to the purest essence of musical expression, the ancestral and at the same time always modern that comes from the human voice alone. A look therefore to the past great polyphonic traditions that finds its reason in a modernity that has now overcome the 'sterility' of many avant-gardes that, through pure research, however, have not reached the completing of the art form.
