Information for Aida at Wembley, Outer London (Opera or Operetta). The essence of Grand Opera first performed in Cairo in 1871. Set in Egypt at the time of the pharoes. A captain of guard (Radames) is in love with Aida, an Ethiopian slave girl - who happens also to be the daughter of the king of Ethiopia. Her mistress, Amneris, is also in love with Radames. When the Ethiopians invade Radames is chosen to lead the army. When they return victorious Radames asks for all the Ethiopian slaves to be released - except Aida and her father who persuades her to trick Radames into revealing the plans of the Egyptian army - but he suggests that they all run away to Ethiopia together. When Radames is accused of treason he gives himself up to let Aida and her father escape but is condemned to be improisoned alive. As the last stones are put in place Aida appears and joins him in the tomb so that they might die together.
