A historically informed performance on Whitsun (Pentecost) Sunday will feature the Mass in C minor, which Mozart composed in Vienna but intended to be premiered in the Benedictine Abbey of St Peter in Salzburg. This concert, dedicated to Mozart’s sacred works, is given by the Baroque orchestra Les Musiciens du Prince — Monaco, the vocal ensemble Il Canto di Orfeo, and their chief conductor Gianluca Capuano. During their residencies at the Whitsun and Summer Festivals in recent years, they have been acclaimed by Salzburg audiences and international critics alike for performances of music from Monteverdi to Verdi.
