A very important page of the contemporary accordion literature, “Vagabonde blu” is a mirror of the aesthetics of the famous Italian composer: research of the noise brought to an extreme sensitiveness, dynamics rarely louder than a “piano”. It shows the physicality of the accordion as an instrument that breath like a lung, sighs and blow in the hands of the musician. “Vagabonde blu” are rare stars which appearance is different than the stellar evolution theory expects, maybe been originated by a collision between two stars.
