Some are on video…others are online.
I like to suggest Groove to show how putting a little extra effort into an event with decor and music will do wonders over the basics in a room.
Maestro is a great documentary on the NYC scene of the 70s and 80s. It’ll give you perspective on where we came from.
Pump Up The Volume is a must to see. Not the Christian Slater movie. Google it online and watch it.
Scratch is nice if you’re into vinyl and turntablism.
Other than that…do some searching in YouTube. Loads of recorded exposes and clips from news reports about things that happened in the past. Saw a good one on the Madchester scene.
