The Quartet Prismo is the continuation of the collaboration of Sergio Armaroli and Fritz Hauser with an extended circle of musicians. Sergio has proposed his wife Francesca Gemmo, I proposed my esteemed colleague Martina Brodbeck. Apart from Structuring the Silence, we recorded combinations of instruments put together by lot. Without time limit, without formal requirements, without rules. Pure improvisation. Together we selected the tracks to be included on the CD and it turned out that the pieces, similar to a prism, made the different instrumental languages light up in different versions. Fritz Hauser
