One of the nation’s most adventurous opera companies, Odyssey Opera, continues its Tudor-inspired season with the fully-staged production of Elisabetta, Regina d’Inghilterra (1815) by Gioachino Rossini (1792-1868). With a libretto by Giovanni Schmidtfrom the play The Page of Leicester by Carlo Federici,this two-act Italian opera contrasts the public and private spheres of Queen Elizabeth I. This seldom-heard work by one of opera’s most beloved composers is the first of the nine Rossini Neapolitan operas. Gil Rose conducts with the soprano Serena Farnocchia as Elizabeth making her Boston debut.
