School of Rock (2003)

Dewey Finn is a guitarist with many delusions of grandeur that lead him to be expelled from his own rock band. Without work or money, he finds a job as a substitute teacher in a private school and all his energy is channeled there, where he realizes to his surprise the musical talent of his students with whom he will create a secret rock band. Directed by Richard Linklater, with an incredible Jack Black, tender and hilarious all at the same time, good music, a lot of soul and rock.
