"This is the whole improvisation session we had on the evening of 25 April 2014, after a day spent recording some duets for Enrico’s project “Girotondo”. In the afternoon I had recorded with Mario Arcari “La prostituta e il soldato”, one of his compositions. The next day I was going to record my song “Il soldato e la cameriera” with Alberto Mandarini. So, during the evening break, after years of not playing together anymore, a little bit on my insistence, because Enrico seemed to want it too, we went back to the studio, and we put ourselves in an unusual position, very far away. Fosca at the mixer. How nice to meet again. And in this way. In the midst of fresh, intense and light music, full of surprises, rich in dependent independence or independent dependence. The only intervention we have done besides mixing is to invert the first and the second track. The titles came two years later, during the re-listening. They have to do with the processes that form rocks from minerals. Heterogeneous materials, rocks, not reducible to formula, with the presence of impurities." - Giancarlo nino Locatelli
