Last season, the Rockford Symphony Orchestra (RSO) and Opera Illinois transported you to Japan for the delicate arias of Cho-Cho-San in Piccinis Madama Butterfly. This year, vocal fireworks explode over Scotlands misty moors as RSO presents Lucia di Lammermoor at 8 p.m., Saturday, Sept. 27, at the Coronado Theatre. Music is by Gaetano Donizetti, Libretto by Salvadore Cammarano, based on Sir Walter Scotts The Bride of Lammermoor, a tale of star-crossed lovers. The performance is sponsored by National City. This piece presents some of operas most memorable duets and ensembles. At the pinnacle of the bel canto operas of the Romantic era, Lucia di Lammermoor is a riveting combination of spectacular singing, taut emotions and soaring melodies. The noble families of Scotland are sworn enemies, the product of an epic feud. Lucia, against all the vagaries of fortune, loves a member of the rival family. But in 17th century Scotland, a woman cannot choose her own destiny. Lucia must give way to her brothers wishes and marry anotheran act that leads to her madness, and to tragedy. Tickets are $48, $38, $28, students $20, and may be ordered by calling Rockford Symphony Orchestra at 965-0049, or CentreEvents at 968-5222.
