Whenever I watch a documentary, I am amazed that the subjects are so candid with cameras rolling. "Rock School" was no exception to that rule. This was the story of a young man (he acts like a big kid) who teaches kids (ages 5-17) how to be rock and roll musicians. He is quite enamored with Frank Zappa and other groups of the 60s and 70s; less so with any more contemporary acts. Many of the kids are misfits who find their place at the Rock School. However, the teacher has quite a foul temper and there are many scenes where he is losing his cool with the kids and quite frankly ridiculing them or cussing them out. As a musician, I have dealt with people having similar personalities, and even though the teacher in this film insists that he inspires the kids with the temper tantrums, I have found that I generally do NOT play better when someone is screaming at me. I concluded that if I had a child at this school, he or she wouldn't be there very long! However, the film itself is worth a look; as a documentary it is informative and entertaining.
