With the 10 arias on Tormento d'amore, Ian Bostridge demonstrates the important place that the tenor voice held in Italian opera from the mid-17th to the mid-18th century - often thought of as the era of the castrato. At this time, there were two main centres of opera in Italy: Venice, where such composers as Cavalli, Vivaldi, Cesti, Stradella, Sartorio and Legrenzi were active, and Naples, home to Provenzale, Caresana, Vinci and Fago. In addition to arias - two of them in world premiere recordings - the album offers five instrumental sinfonie and a traditional Neapolitan song, 'Lu cardillo', or 'The Goldfinch', a songbird closely associated with Naples. Bostridge is partnered by conductor Antonio Florio and his ensemble Cappella Neapolitana.

Known for her idiosyncratic performances of baroque repertoire and eccentric personal style, the German coloratura soprano Simone Kermes trained in her native Leipzig, with early successes including the International Johann Sebastian Bach Competition. Bach has not, however, figured prominently in her career since then – Kermes gravitated towards Vivaldi, Handel and the Neapolitan composers who wrote for the great castrati, such as Riccardo Broschi, Alessandro Scarlatti and Porpora. (She has recorded several solo albums of such repertoire for Sony, including Dramma, and Colori d’Amore – reviewing the latter, BBC Music Magazine described her as ‘a remarkable artist, charming, fascinating and boldly risk-taking by turns’).
