With war and acts of violence in the background, Aida tells the story of a fascinating and tense love triangle between the Egyptian princess, Amneris, Ramades, an officer, and Aida, a Nubian princess, captured and reduced to slavery. The historical scenes and triumphal marches, which have contributed to the popularity of this opera, are followed by intimate but powerful duets and introspective moments of great intensity.
