For many, contemporary classical music is something foreign and distant, and when it is then defined as "cultured music," it is easy to turn away from it and judge it as hostile. But the opposite can also happen: what seems listenable, or even enjoyable, is not considered "classical music" or is excluded from academia. As was sometimes the case with the eleven composers Carlo Boccadoro wanted to interview, so that everyone – public and critics alike – could get to know them better. Musica coelestis takes the reader-listener into their homes, offices, hotel rooms, for an informal, never trivial chat, discovering a world rich in sounds, inspirations and ideas, in which these composers tell their stories freely, delivering us their self-portraits.
