Francesco Cavalli succeeded Monteverdi as the most influential composer of the new genre of opera that emerged in mid-17th-century Venice. Il Xerse is a fictitious dramma per musica that tells of Persian King Xerxes’ love for Romilda, who in turn is in love with his brother Arsamene. The plot is an entertaining and extremely intricate human comedy of crossed loves, court intrigues and disguises – the work’s popularity saw it staged in Paris at the wedding of Louis XIV and Maria Theresa of Spain. Since overshadowed by Handel’s later Xerxes, this Martina Franca production is the first in modern times.

For his second recital album for BIS, countertenor and sopranist Nicolò Balducci, ‘a singer of a remarkably sweet sound and distinct vocal agility’ (Gramophone), presents arias that evoke love and pain, two basic ingredients of Italian opera in the 18th century. Often tailor-made for specific singers who were in some cases the foremost castrati from that era such as the legendary Farinelli, these arias expressed resolute valour, unbridled fury and sometimes extreme guilt, to the delight of audiences that enjoyed these operas with their far-fetched narratives inspired by mythology or historical events.

During the 17th and 18th centuries, Naples’ fame as a musical centre attracted travellers, composers, instrumentalists and virtuoso singers alike. Among the aspiring musicians, the most highly-trained and sought-after were the castrati, promising boys aged between 8 and 12 who were subjected to an operation intended to preserve the exceptionally pure timbre of their treble voice. Forever virginal beings whose superhuman voices mesmerized their listeners they were nicknamed angiolilli, ‘little angels’, and sang in the most important churches and theatres of ‘Castrapolis’, a term coined to describe the southern capital and its high concentration of castrato sopranos.
