What is the title of the piece that features Escamillo singing an aria?

The piece featuring Escamillo singing an aria is known as the "Toreador Song" from Carmen. This iconic aria is performed by the character Escamillo, who is a bullfighter, and it captures the vibrant atmosphere of the bullfighting arena, filled with themes of bravery and passion. The song is celebrated for its energetic melody and is one of the most recognizable pieces in the opera repertoire, showcasing both the dramatic elements of the story and the character’s larger-than-life personality.

The other options do not contain this specific aria or character. In "The Magic Flute," the focus is on different characters and themes unrelated to bullfighting. "Madama Butterfly" centers on a different narrative involving love and tragedy, with no connection to Escamillo or the Toreador Song. "La Traviata" tells a poignant story of love and sacrifice, but again does not involve Escamillo or the celebrated aria in question. Thus, the "Toreador Song" is distinct and specifically tied to the character from Carmen.
