The documentary 'Heavenly Voices - The Legacy of Farinelli' (2012) tells us the story of the castrato in music - male singers who were castrated at a young age in order to preserve their high vocal range, a cruel practice that was in place mainly in the 17th and 18th centuries. For two centuries, castrati's performances held European audiences spellbound, with successful castrati such as Farinelli ranking among the most influential and highest-earning musicians of those days. Today, roles originally written for castrati are often performed by countertenors. In this documentary, countertenors Max Emanuel Ceni, Philippe Jaroussky, Andreas Scholl, Franco Fagioli, and Jochen Kowalski discuss Baroque-era operatic entertainment. 'Heavenly Voices' is a film by Gino Pennacchi (writer) and Alessandro Scillitani (director).
