One of the most authoritative voices of Italian and international jazz traces the artistic evolution and the historical path of the African American music, from its origins to the present day. Through his experience as a musician and teacher, Liguori shows the thousand facets of the music that more than others marked the twentieth century. A compelling narrative, exposed with a wealth of details but also with anecdotes experienced firsthand. As in a novel, the book tells the story of jazz from Africa to New Orleans, up to the radical and revolutionary waves of the 1960s. At the same time, he follows the artistic evolution of Liguori with his human and musical story, which develops from the 1960s onwards. The radical nature of his positions and the absolute sincerity in supporting them have made Liguori not a mere witness but a protagonist of the cultural, educational and musical scene, as evidenced by the record critics award obtained in 1978. With unstoppable passion for a musical language that remains the most important novelty on the music scene of our times, the book tells three stories that integrate: the evolution of jazz, from theories to genres, the personal experiences of the author and his encounters with the Italian and international protagonists of this music. The book ends with the most beautiful records in the history of jazz according to Liguori.
