Staff Reporter A concert performance of Bizet's opera The Pearl Fishers will be given tomorrow at 10pm on the patio of the Misericordia in Palma. This will be part of the Fundacion Teatro Principal's 20th opera season. The Foundation will also produce the show, which was presented yesterday by its managing director, Gabriell Coll; the conductor of the Foundation's choir, Francesc Bonnin; the musical director of the work, Gianluca Marinenghi; and by various members of the cast. The opera is in three acts and tells the story of Nadir, a pearl fisher, and Zurga, the boss of a fishing village, who are both in love with the same girl, Leila. The cast includes the Italian tenor Giorgio Casciarri, the Italian baritone Silvio Zanon, the Russian soprano Alina Furman and the Spanish bass Felipe Bou. During the presentation, Bonnin said that The Pearl Fishers, which will have the participation of the Balearic Symphony Orchestra and the Foundation's choir, is one of Bizet's lesser performed works. Marinenghi said that it is a less symphonic opera than other works of Bizet, such as Carmen, and explained that in this opera there are many solos, whether they be vocal or instrumental. The musical director said that this is a surprising opera because in spite of not have much orchestration, what there is stands out for its beauty.
