Britten’s opera The Rape of Lucretia is, as the title implies, not an easy opera subject-wise. It is based on André Obey’s play Le viol de Lucrèce, which in turn is partially based on Shakespeare’s poem The Rape of Lucrece. This was Britten’s third opera, and the first of his so-called chamber operas, operas with small orchestras and small casts.
