Elsie's music class has played Twinkle, Twinkle, Little Star too many times, and she wants to try something new. When her music teacher suggests she "rock on her own time," Elsie devises a plan. It's recess, and the playground will make a great venue. Soon she and her best friends are setting up a stage. In true rock-star fashion, their band enlists classmates to help with hair and makeup, special effects, and security. They even host a press conference and an autograph session! Elsie has thought of everything to throw the most epic of recess rock concerts ... or has she?
