This was a 1988 revival of a 1971 production that teamed Domingo (Vasco da Gama) and Verrett (Selika - both then very much in their prime) in Meyerbeer's discursive swan-song. Seventeen years on, they are more statuesque than sexy, but both give larger-than-life performances that contain moments of completely thrilling vocalism. The casting is very strong, with the exception of Justino Diaz's Nelusko, which has strong presence but not much vocal allure. As Inez, Vasco da Gama's fiancee and rival for Shirley Verrett, Ruth Ann Swneson sings with great beauty and has impressive stage presence, very much holding her own in the confrontation with Verrett in the last act. Domingo is refulgent of tone and dramatically convincing, and he and Verrett strike sparks. She really comes into her own in one of the most preposterous mad-scenes in all opera, where she is slowly poisoned by the scent of a giant tree, contriving to make this dramatically truthful and even moving.

The ambiguities of Verdi’s theatre are particularly clear in his baritone roles, among which is that of Boccanegra, corsair turned doge of Genoa and the troubled observer of the conflicts that tore apart 14th century landowners and peasants. An eminently political opera in which power struggles are interwoven with family conflicts, Simon Boccanegra echoes the life of its composer – the man who championed the cause of Italian unification and overcame the loss of his wife and children.
