This new release is an opportunity to discover a set of innovative solo and accompanied works for the flute, composed over a forty-year period by Claudio Ambrosini, which have so far remained inaccessible: while they have been repeatedly performed in public they have never been recorded or published. Listening to these works, presented here for the first time in a systematic manner, finally makes it possible to clearly appreciate the importance of Ambrosini's contribution to the development of the literature and the extended linguistic features of the flute since the end of the 1970s.
