**200 copies** "Not knowing is my fifth accordion solo and a new challenge for the instrument itself, here treated as an object in space. Whereas in the other recordings the centre of attention was put in materiality, structure or deconstruction, with microphones extremely close to the instrument, almost inside it, here the point of inflexion is the architecture and space as an essential part of the recording. It's still with an exploratory intention that I try to blur the limits of what to expect and, by extension what to identify. Not knowing expresses both this change and through its title, the contradictory nature of my intimate relationship with such a complicated instrument." - Alfredo Costa Monteiro
