Italian web sites seem to often announce performances online at the last minute. A single performance of Zanetto will take place tomorrow, Thursday February 14, 2008 at 9 PM (21:00) the Teatro Sarti in Faenza, Italy.
This is part of an event called "San Valentino al Teatro Sarti " ("Valentine's Day at Teatro Sarti"), which seems to include some music and a buffet. The performance will be done without an orchestra and simply a piano accompaniment. The performers are as follows:
Manuel Mensà: soprano
Ottavia Sisti: soprano
Pietro Mariani: conductor, piano accompaniment
Tickets cost EUR 20 and are available online at http://www.manuelsoprano.com/.
