  • @francesco, I think a better question is the simplest question: "what exactly does the blackboard say?"

This poster is $45 for an “archival paper” print, but it only goes up to 1978.

The contents of the School of Rock blackboard were transcribed like this;

    I like how this redrawing makes it look like KC & the Sunshine Band might be a rap group. (Or that Dr. Dre is disco.)

  • It's a pity there is no commons family tree of rock otherwise we could all learn so much from this :(

Jack Black explained on the Watt from Pedro podcast that the director, cast and crew filled it out. He wanted to make sure the interviewer, Mike Watt, knew that he had added in Watt's band, the Minutemen, because he is a huge fan.
