In 1985 LL Cool J was hired to play a show with Cut Creator in Portland, Maine. He puts on a great performance even the show doesn’t appear to be well attended, or have a very enthusiastic audience. From the YouTube uploader:
LL was paid $500 for the show. Since he was the only rap act, he was worried it would a be short performance, so my dad suggested he fill it in with the scratching and beat boxing.
LL was signed to Def Jam. My dad tried to get RUN DMC, but could not afford them, so Def Jam told him he should bring up LL Cool J.
