home with his mother Lisa. There is a montage of scenes of the students rehearsing for a beginner's Black Sabbath show, and an 80's show by the intermediate students, and interviews with other students including Eric and Julie Slick, and keyboard teacher Eric Svalgard, father of Madi Diaz. Green confesses that, if the school is successful, the students will become better musicians than himself, followed by his personal history and introduces his wife Lisa. A clip of Zappa musician Napoleon Murphy Brock is played for the students, and Green talks about getting the students to play Zappa's notoriously difficult music. The All-Stars have been invited to play the annual Zappa music festival Zappanale. Green and various students are interviewed about the upcoming event. Diaz is interviewed about a side project with her Quaker friends, the Friendly Gangstaz who rap traditional Quaker hymns, which Green mocks. Tywoniak's parents discuss their son's focus and drive. Andrea applies make-up to her son Tucker and dresses Asa's hair into the Mohawk hairstyle seen on the film poster in preparation for the twins' Black Sabbath show while singing the song "Sweet Leaf". Several Black Sabbath songs are performed at the concert including "Sweet Leaf", "Paranoid" and "Iron Man". Green delivers a ranting, profanity-laden halftime speech during the intermission of the show. On the commentary track, the directors reveal that the MPAA informed them that the film was rated R, and had 38 usages of the word "fuck". The location switches to Green's home and a scene with his infant son Walden, who dances enthusiastically to a Zappa song. A title card reveals that Tywoniak had to undergo emergency orthopedic surgery two days before a concert. Green introduces him at the concert, revealing that Tywoniak would not undergo the operation unless he could play the concert. Back at the school, Green tells the students that Melissa Dribben, a reporter from the Philadelphia Inquirer newspaper, is to do a feature story on the school. The article is critical of Green and his methods and O'Conner says that it "was written with the composition of a fourth grader". Dribben had called O'Conner "the sad Eeyore of Rock School", and revealed a Green joke about the "Will O'Conner Award for the Student Most Likely To Kill Himself". This caused considerable friction at O'Conner's home, resulting in him leaving the school. There is another montage of rehearsals for the 80s
