In this anthology, which is a portrait of his compositional tendencies, Claudio Ambrosini is actually one of the most daring creators of utopian virtuosity; a virtuosity which is grounded in the invention of multi-formal, luminous, permutable, nocturnal sound, giving prerogative to an exasperation of extremes and matured in the workshop of the Ex Novo Ensemble, a permanently active workshop of constantly renewed research. It is also a dream of a liminal avantgarde that favors torrential energy but at times opens up into a voluble undercurrent of song: a furtive shadow of Maderna appears.
