Paul Green is a man who declares himself born to teach kids, but he has nothing to do with the traditional educational system. Musician Green is the proprietor of the Paul Green School of Rock Music, an after-school facility in Philadelphia where kids from 9 to 17 learn how to play instruments and work together in a band. While Green outwardly seems like a loose cannon who yells at his students and acts only marginally more mature than a high schooler, the kids who attend his school love him and he gets results; one of the Rock School's ensembles were invited to perform at a Frank Zappa tribute event in Germany (where they brought down the house), and several say that his approach has changed their lives for the better. Rock School is a documentary which offers an inside look at Paul Green, his school, and the kids who learn from him.
