TOSCA: Giacomo Puccini, 1900. Opera diva, Tosca, tries to save her republican-sympathising lover, the painter Cavaradossi, from the jealous revenge of the venal Chief of Police, Scarpia. The tragic dénouement leaves all three dead. A new commission from the Oxford Opera Company, this version has a contemporary, Latin-American slant, easily adaptable to a more traditional reading.
