How old school is this 1985 LL Cool J performance? Well, aside from the fact that this was shot a good five months before his debut album Radio came out, he felt the need to explain to his young audience what they were about to witness:

“What you’re about to see right now is called rapping and scratching. How many of you saw this before?”

Shot on June 21, 1985 at the Wadsworth Gymnasium at Colby College in Maine. There’s an interesting context: this was part of an event to cheer kids up after several recent student suicides in the area and LL Cool J was thought to be a positive role model.
