Have a look at this great piece of hip hop history. It's LL Cool J rocking a school hall just a few months prior to his RADIO album being dropped on Def Jam.
Make it past the awful scratch antics of Cut Creator and you'll be rewarded with the ever-confident vocal delivery and showmanship of a young, 17-year old James Todd Smith.
Check out his human beatbox. Why did he never exhibit this on record?!
Thanks to JUST-1 for finding this.
