The forewords are by philosopher Massimo Donà, musicologist Carlo Boccadoro, and Franco Caroni, president of Siena Jazz; the book also contains many other contributions, including those by Ashley Kahn, Stefano Zenni, and Flavio Caprera (in 2020 the second expanded and updated edition came out).
Nat Hentoff, one of America's leading music critics, wrote of him, "What strikes me most about Claudio Fasoli is the clarity and individuality of the narrative; he really 'speaks' with his horns, his reeds.
Fasoli's voice reveals his thoughts as he speaks directly to each individual viewer and helps us to enter the evolution of the creative process, and its key concepts such as time, improvisation, silence, subtraction, risk, unpredictability.
When Perigeo disbanded in 1978, he became leader of his own groups, putting together mostly trios or quartets, with Aldo Romano, Bill Elgart, Bobo Stenson, Henri Texier, Jean-François Jenny Clark, Kenny Wheeler, Lee Konitz, Manfred Schoof, Mick Goodrick, Palle Danielsson, and Tony Oxley.
In addition to his native Italy, he has performed in France, Switzerland, Jugoslavia, Poland, Germany, Holland, Belgium, Spain, Finland, Luxembourg, Denmark, Sweden, England, Ireland, Canada, Mexico, Cuba, and the United States.
