i wish there have be something like this when i be young rather than my 70 year old music teacher who have no idea what be go on in the music i be listen to at the time other than the certainty that that not music that just loud bang and scream . it one thing to understand note and technical aspect of be a musician but an understanding of attitude and performance and vibe and etc be a necessary trait that most music instructor lack . i get a kick out of watch him treat the kid a peer instead of condescend to them . great finale as well . i really dig the movie . teach kid to rock be a noble call indeed positive . can not wait to see it again when it come out proper .
