A rock opera is a theatrical work that combines rock music with a narrative storyline, often presented in the form of a musical. Unlike traditional operas, which typically use classical music, rock operas feature electric guitars, drums, and other elements of rock music to convey emotions and advance the plot. These productions often explore complex themes and characters, making them appealing to a wide audience. Notable examples include The Who's Tommy and Andrew Lloyd Webber's Jesus Christ Superstar, both of which have gained significant popularity and have been adapted into films and stage performances.
