Library Starter - the Silver Statue

Kate loves singing and playing her guitar - and she's good, too. One Saturday, she goes to the town square with her friend Lucy, and plays there. It's a big thing, playing in front of people, and Kate isn't the only street performer in the square that day. The silver statue is there, and that's OK because she never moves or speaks. But Joe the drummer is there too, and Kate's music and Joe's drums aren't good together. Or are they?
