The band is excited for the Maestro's performance in the fourth book of this laugh out loud series starring four musical instruments in their first year at Band Camp! Zook can't contain himself when world renowned composer Maestro Talenti graces the camp with his presence. Zook's big dream is to be the first kazoo to ever be featured in a symphony orchestra, and with the Maestro arriving he sees an opportunity to make that a reality. But much to Zook's disappointment, the Maestro turns out to be a total snob; he scoffs at the mere suggestion that a kazoo could ever join him on stage. Can the group help Zook convince the Maestro that he can play in tune?
