It's a documentary, about the music school that inspired Jack Black's "School of Rock." Before hearing the back story, I enjoyed "School of Rock," only to find that the real school and instructor were never paid a penny by the producers of the more successful comedy. They did visit the school, but then rather deceptively told the real teacher that they changed their mind, and made the Hollywood version without so much as a decent "thank-you." So, in terms of economic justice, I would like to see more people buy this documentary. It is a much more interesting story than the fictionalized version, it's a story of a remarkably successful music teacher. If any late 20th century rock 'n roll is still being performed a century from now, Frank Zappa will be known as a composer, not a rock star. His music is strange, original, and quite complex. It's not easy for professional musicians to play. But at this children's rock music school, kids learn to get good at playing rock music, and some become so adept at difficult rock that the best group competes with adults at an international Zappa festival. The documentary actually follows the underdog sports movie plotline, so you'll end up cheering for these talented children. I highly recommend this movie to musicians, there's an underlying story about that combination of hard work and passion that transcends musical genres. I also highly recommend this documetary for serious educators, jaded by the edu-speak education "experts." This documentary, plus the very real life documentary, "Stand and Deliver," tell parallel true stories about the most successful teachers, who don't try to treat all students the same way, who don't dumb-down to the bottom third, who don't make up words like, "competencies," or "multiple intelligences." In fact, both Jaime Escalante of "Stand and Deliver" and Paul Green of "Rock School," shared some opposite pedogogy to the current fashionable trends, they were both rather mean and demanding at times, with very high expectations, and identifying the students with the most potential and driving those students to higher achievement earned remarkable results in both music here, and math in "Stand and Deliver." In an America that seems to have collectively embraced mediocrity, it's refreshing and inspiring to see the story of a teacher who successfully drives his students to creative excellence via hard work.
