In Spiritum is a project born from the friendship and collaboration of Federico Bracalente and Daniele di Bonaventura, with the idea of merging the sounds of their instruments, the cello and the bandoneon, into a single sound organism.

The repertoire is chosen from three-voice polyphonic vocal literature, both sacred and profane, with the idea of re-elaborating it through the insertion of free and improvised parts. Taking advantage of the vocal characteristics of the two instruments, the wide range of the cello and the two liturgical registers of the bandoneon(left hand and right hand), the music sounds as if there were three singers, placing it in a new instrumental timbral context.

Presented are works by Mouton, Dufay, Agricola, Binchois, Palestrina and works by bandoneonist Daniele di Bonaventura.
