Fictional bands are musical groups that exist only in books, movies, television shows, or other forms of media. They are created to enhance storytelling, often reflecting the culture or themes of the narrative. Examples include The Monkees, a band formed for a television series, and The Blues Brothers, known for their comedic performances in a film. These bands can have a significant impact on popular culture, influencing real-life musicians and fans. Their songs, often written specifically for the story, can become iconic, as seen with Spinal Tap, a parody band that satirizes the rock music scene.
