Ever see the pitch-perfect 2003 Jack Black comedy School of Rock? Then you know what to expect from the musical version: fake substitute teacher Dewey Finn frenetically inspiring his charges to release their inner Jimi Hendrix; uptight preppy tweens learning classic riffs; and the band’s pivotal, make-or-break gig, with their overbearing parents watching in horror. We expect cute kids in uniform, a spastic Dewey and face-melting riffs—along with heart-tugging family stuff. It worked for the movie, and wow, does it work on Broadway, a double jolt of adrenaline and sugar to inspire the most helicoptered of tots to play hooky and go shred an ax. For those about to love School of Rock: We salute you.
